"I listen to this record all the way through - even 'Moby Dick'. To me it encapsulates the Led Zeppelin sound, because the engineering on it is so magnificent. The fact that a four-piece band can sound so vast. Obviously there are great tracks on III and IV. But I feel that II is the most complete album. It's amazing to find out they recorded it mostly on tour. Extraordinary. It sounds like it was recorded in one room. I think it's accounted for by the fact they just sound like that. They just sound that magnificent. I was not a huge fan of the first album. I remember reading the story about how, I think it was Glyn Johns again, the story about him playing it to George Harrison, and George Harrison didn't really get it. I wonder if he had played him Zeppelin II he'd have got it. I is not my favourite. On II it felt fully realised. They'd pulled away from that influence of blues; it was still there, but they'd merged it into their own thing. Which again I think is something that people don't associate with Simply Red – we've been enormously influenced by African American music, but we've been influenced by it from a different era. The marriage between black and white started with Bing Crosby and Frank Sinatra and George Gershwin and all these people that ran through music, right through to Elvis, to Jagger, to Robert Plant – we've all in our own ways been enormously influenced by African American music. But the real thing to celebrate is that we made something different out of it. We didn't just copy it. The British especially turned it into something else. It became what we now know as rock music. The Beatles and the Stones are the people who can justifiably claim to have invented what we know as rock music. Not rock & roll, not R&B, not blues, but rock. And that is something to celebrate."

"The thing about that record is that it had an honesty that rock & roll had been missing. The 80s were a terrible time when guitars didn't sound like guitars and there were drum machines, but then all of a sudden here comes this group, Guns N' Roses who plug in their guitars and just didn't mess around with any fancy stuff. And the songs were undeniable! 'Welcome To The Jungle' is an undeniable song in the same way that 'Satisfaction' has that great riff with the lyrics on top of it. Great lyrics, great imagery, and as soon as you heard that high-pitched voice that harkened back to a Robert Plant-ish approach to singing, which hadn't been heard in quite a while… Well, it still works today. That's got to be coming up to 30 years old, but you put that on today if it was a brand new band, I would say, 'Who's that?' That intro is almost symphonic, and it just defined the band. You hear that song, and then the rest of the album follows through. 'Welcome To The Jungle' is head, hands and feet above the other material. Bands have a few songs that just stand up, you know? You think Thin Lizzy, you think 'The Boys Are Back In Town'. You think the Stones, you think 'Satisfaction'. You think Led Zeppelin, you think 'Stairway To Heaven'. There are just certain songs that, either because of the melody or lyric or the sound of the song, intrinsically say, ""This is what that is"". The only band who doesn't have that thing, just because they have so many god damn good songs, is The Beatles. I don't know if [us influencing them] is the case. We never paid attention to anything. There can be scenes or not and people can be influenced or not, but at the end of the day you are left to your own devices. When you think about it, The Beatles were influenced by Motown, The Everly Brothers, Chuck Berry, etc. but then when you hear The Beatles, it's their own stuff. It's like cooks. Everybody uses salt, everybody uses vegetables, there is nothing unique, but how you mix up those elements makes it yours or not. If you can grab a style, I think it has to do with talent. Everybody cooks, but few people are cooks."

"Last year I arrived in San Diego at the beginning of a tour, where I was playing the Thick As A Brick material. I ambled down to the theatre in the morning having arrived the night before, where the theatre manager said there was a note for me in my dressing room, left behind by Alfie Boe who they’d had a couple of nights before. I recognised Alfie Boe as a hotshot, super popular opera star who played at the Queen’s Jubilee Concert in Hyde Park. They crop up from time to time, these people who cross over from a more insulated music into wider popular culture, and Alfie Boe has certainly done that in the last couple of years with opera music. You might think he’s just another of the usual not-quite-authentic people who just find themselves singing the odd aria at working men’s clubs, and getting a record deal and a ton of money. But Alfie did his apprenticeship by studying at the Royal Academy of Music, worked with the D’Oyly Carte Opera and spent ten years of his life learning his craft. And he was a man born with enormous natural talent. Rather like Lou Gramm he has this very assured level of control – he knows what he can do. I read his note to me, wishing me a good show and leaving me a phone number. So a few weeks later in England I called Alfie and we had a few chats on the phone, and though we haven’t met we were due on two occasions to have lunch, but he had to cancel because of his mother’s illness. But I hope I do get to meet Alfie because I think he’s a very fine singer. I understand that while his desire is not to leave classical music, he wants to demonstrate he’s got the cojones of a Tom Jones or a Robert Plant or whoever - he wants to be a rock and roll singer. Far be it for me to say that might be mistake, you’ve got to give it a go. So Alfie’s branching out into rather middle-of-the-road pop and rock at the moment. As a classical singer, I think he has the gravitas and vocal expertise, perhaps more vocal expertise, than Pavarotti at his relatively young best. If you listen to Alfie’s ‘Nessun Dorma’, I think you’ll hear something that is sung with enormous technical ability, control, authority and with the right amount of gravitas, it has a weight to it that I think is really great. I hope he doesn’t sell himself short in the realm of middle-of-the-road pop music."

"Foreigner was a band that had an anthemic sophistication about their musical approach. It was educated, well-formed, well turned-out British-American music. The primary songwriter and leader of the band [Mick Jones] was a Brit, and the vocal talents of probably rock’s finest ever tenor, Lou Gramm, fitted perfectly with their sound. I got to know Lou many years later after his horrendous illness. When he was making his comeback to singing after brain surgery, me and some other guys played with him on a big German TV show, and we had to change the key of the song we were doing. We dropped it before he came over to Germany and then when he got there we dropped it another couple of steps. I said to him that the Lou Gramm of 20 or 30 years prior, when he was singing at the top of his range, was a pretty hard act to follow. He said that he didn’t write the songs, and just had to sing what was written, and that he could do that in the studio but it was very tough to do night after night on stage. In a sense I have been there myself. I made records in 1982 [The Broadsword And The Beast] and 1984 [Under Wraps] where I sang really well on record, absolutely at the top of my range. I’m a baritone, and my range is usually up to an E or an occasional hasty F, and then I was singing F# and G. I was singing at the top of my range and singing consistently up there, not just the occasional high note. It was something I couldn’t keep up night after night and I lost my voice in 1984 and had to pretty much take a year off to recover. I cancelled three shows in Australia and two shows in the USA. Over the period of a month I cancelled more than 50 per cent of all the shows that I’ve cancelled in my entire 44 years in music. I still have a soft spot for Lou because of his incredible vocal ability and the wonderful controlled quality of his voice. I do believe he is rock’s finest tenor. His diction was good, his articulation and rhythm was great, he was a truly great singer. It doesn’t mean he’s rock’s best singer or best-known singer, because the usually out of tune Rod Stewart and gymnastic Robert Plant were probably more charismatic. Lou was more mainstream, but it was nevertheless a joy to listen to someone, rather like Alfie Boe, who is in complete control of their vocal ability as the result of hard work and a huge amount of natural talent. He may not be the most exciting pop singer, but for me he is the best."
