"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."
