"I think the period from 1979 to 1982 was the best period for British pop music. And out of all that stuff it's 'Oliver's Army' that I've chosen. It gets more incredible the older I get and the more I understand about it. Visually, when it first came out, Elvis Costello was like a Halloween version of Buddy Holly. It's all distorted - his clothes were too big for him and his glasses were too big for him. He didn't look like a very nice guy - quite frightening - but singing this amazing song. Some songs will move your feet, emotions, and some will move your head - and this has got all of this, all together. I knew all the words. I'd write the words down in my exercise book at school, but I didn't understand any of it. But they're such good words you don't really have to. I love that first line: "Don't start me talking/ I could talk all night". It just brings up that image of youthful idealism - we can sit up all night talking. Before you get into drink, drugs and all that, you just sit up talking because you can. I love that. It could Paris in the late 60s, or London at the end of the century, or Greenwich Village. Musically, I just read about the piano part... Elvis didn't like the song at all and they were going to scrap it, so the piano player suggested, "Why don't we play something like ABBA?" I think it's 'Dancing Queen'. And then they put that on and that was it. But no one wanted to say yes at first as it wasn't a very cool thing to do."

"They'd made three albums before this that had the hits on and some other stuff that was really good, but I never really liked a whole album. There were great moments. But then Caravanserai came out and I liked the way the songs move and flow and change direction and bring in different moods and atmospheres. It was a very exotic record for me, living in Kingston in Surrey. It felt like I was hearing the real sound of the desert. The musicianship is so great. One of the things I love about Santana is that they always had great drummers. Obviously you've got Carlos on guitar, but every instrument is pushed to the front. When the Hammond player is letting rip you can really hear it. It's a very well-structured record, which back then was a very different thing to do, because it was all about the live performance, and if the song was eight minutes long you'd play for eight minutes. There wasn't the technology for any sophisticated editing so people used to play it that way to create that mood and that atmosphere. To capture that in the studio is difficult, but on this record it kind of goes beyond that. It's like somebody said there are no rules for how you do this. I don't know how to do this so I'm going to do this by instinct, I suppose. Also, for them to come in with Latin music that wasn't salsa or mariachi was unheard of. They were saying 'this is what young Mexicans do'. I just remember watching them at Woodstock and seeing [Santana drummer] Mike Shrieve and thinking my god, how do you do that? How do you play with all of them at the same time and they're all playing different things and it all works out so remarkably well?"
