"I often listen to Simon & Garfunkel now and think they’re terribly produced, but they’re certainly a band who are perfect performers on record. There’s something to be said for their restraint; on a lot of tracks you think there might be a drummer but it’s just so quiet in the mix. When you think about what The Beatles were producing at the same time it’s kind of crazy actually - but it doesn’t matter, because their voices were always there when you needed them and that was all you were listening to essentially. They would supply the harmony for each other, as well as the melody and the words. “’Wednesday Morning, 3am’ has got this absolute perfection to it. Fleet Foxes get pretty close in terms of recording multiple voices, but it’s not somewhere people tend to go. I loved it so much, because you could sing with it and you didn’t even have to sing either of their parts; there was always room for more. I always liked choral music growing up, but I felt that this was what choral music should be doing. “I’ve always loved this particular song: just the sadness in it, the description of his girlfriend and the description of having to go because he’s committed a crime. It’s a really weird angle about these few hours he’s got left and it makes me sad every time I hear it. There’s loads of stuff that I didn’t understand in it too: a ‘hard liquor store’ for example. I had no idea what that meant! But they went to dark places. “By the time I’d heard something like ‘7 O’Clock News/Silent Night’ the whole collage thing had been done so much and it didn’t seem that powerful to me. You’ve seen a hundred films that do it now and having sample speech in songs isn’t that crazy. But I bet when it first came out it would have been pretty amazing."

"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."
