"This had a massive impact on the way my parents brought us up, especially my dad, who's a singer himself. Here were a family from the North digging into old songs and traditions, and it made Dad really interested in doing the same. He became a member of a longsword team – I know – and then he got into reviving Mummers' plays, including the only surviving Mummers' play including its own dance. Every Boxing Day, us kids would be dragged down to see it, Dad playing this character who would be killed and brought to life again [laughs]. So many of our rituals as a family were about similar things: carolling on the green, singing folk in the pub and having this real passion for the seasons. For me, revisiting tradition is very rooted in wanting to recognise social struggles, the situations of the working classes, and the pastoral. These songs aren't about looking backwards and inwards, but about learning about the realities of your culture and wanting to share it with others. I remembering going to a Swedish festival some time ago, being encouraged to share songs from where I was from, and realising then what a very powerful currency those songs were. They help you connect with other countries' forgotten stories and emotions – and actually, that's something that happened to me in Harare doing Africa Express as well. These Ethiopian women encouraging me to sing for them, and then watching their reactions… it's very moving seeing people respond to these songs from different parts of the world. It makes you realise there's so much that connects us."

"This was originally going to be last but instead I put Alfie Boe last, and I thought I’d bookend things with classical music, without wanting to sound snobbish. Actually I do want to sound snobbish – there’s nothing wrong with being snobbish when what you’re being snobbish about is the gold dust of our musical worth. Beethoven to me is the consummate classical composer. He learnt stuff from Bach, and Mozart, but he came at a time when he could bring all of his many influences together and not only from the classical tradition. He had an awareness of folk music and rhythm that I think is demonstrated in the ninth. The scherzo from the ninth symphony is a very rhythmic affair and one of those occasions where he utilised elements of rhythmic folk music, which is kind of interesting I think. A lot of composers looked down on the traditions of more naïve music forms but Beethoven seemed to recognise their worth. And of course towards the end of his days he would leave the symphonic work behind and concentrate on string quartets, and that again is a very disciplined, controlled fine art in music, to work with finite musical resources and treat them almost as if they are a symphony orchestra. So Beethoven is kind of the guy for me, he’s the top man. I probably first became aware of Beethoven’s ninth through A Clockwork Orange and that took me through the electronica versions of Walter - now Wendy - Carlos, and then to the original score by von Karajan. That is the one I still enjoy best to this day, the Sixties Deutsche Grammophon recording, where the tempo’s just right. I’ve listened to lots of other variations that are too fast, too slow, a bit sloppy, too cacophonous, but von Karajan in spite of his rather dictatorial nature, did the job."

"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.
