"I heard this on the radio in the States, and I loved the songwriting. He was coming up with something different, it was a soulful folk, so I went and bought the album in LA, I thought “I gotta hear what this guy does” and every bloody track on it is a gem. I’ve always loved the sound of an album, maybe as much as the songs themselves, you know the performance, the sound of it makes a big difference to me. And now you know you can get box sets with alternate takes, and you realise then how long it took them sometimes to get the final take. The first time they did it was good, but then all of a sudden - boom - and there it is. I think there’s a good learning process to listen to the ones they didn’t let go, where the producers said “not yet”, and they persevered until... there it is. When I’ve been in a club sometimes, I’ve gotten up [on stage] and they’ve been like, “Do ‘Delilah’!”, and I’ve said “Let me just do this, which I don’t normally do"". So it is, because when you’ve made big records - great onstage, the way you do your own show - but it’s great to do other stuff when you don’t have to do those things. Not that I don’t like them, you know ‘Delilah’’s a great record, but its nice to do other things. So when you hear someone like Bill Withers doing something like that and being successful, you think, “See, there’s room for that.” There’s room for all different kinds of records. They don’t all have to be the same, or in the same vein, or chasing some things just to get a hit record."

"That said, I love the more ancient sides of British culture as well. This reminds of a really broody, Autumnal day years ago – when there was all this low, grey cloud – when I decided I was going to go to the Avebury Stone Circle. When I was first there, it was deserted and perfect. 

A little while later, I heard a break in the quietness –someone else had arrived. Then I heard these big footsteps, and Robert Plant – Robert Plant appeared from behind a stone! It was an absolutely perfect moment.

I was too shy to say anything, of course, but when I was leaving, there he was at the car park, and, argh, his car was next to mine. I got into the driver's seat, I caught his eye, so I wound down the window…and I just couldn't think what to say, so I just grinned and gave him a big thumbs-up! We've met properly since, but whenever I think of Led Zeppelin, I think of him emerging from the mists like a druid.

I also didn't hear this until I was 27, and then I was all, oh, no wonder they're so popular, this is fantastic! Music was tribal to me when I was a teenager. I was a real indie kid who didn't listen to rock at all. Now I listen to it often, and I think of the house where they made this album, the other side of the mountains to where I live, and it really feels like this music comes from this very old, rooted place. And 'The Battle Of Evermore', with Sandy Denny's voice – I love how the whole of the end-of-the-60s British folk moment is caught up in the way she sings. I love the way those traditions connect us to something deeper.
