There's always something in most world folk musics that always seems connected; whether it's a bagpipe or a tambura, there's always some sort of drone instrument, and there's always percussion.

The Zombies were really unique - they had elements of jazz and classical music in their songs and songwriting. They had a very, very different sound compared to a lot of their contemporaries at the time.

I don't know if there's any formula. I'm not sure I believe in that, to be honest. I don't know if there's any rhyme or reason to music. Sometimes it hits and sometimes it doesn't, really.

The first thing I bought that was really stylish was in 1969 when I was eleven. I saved up for a black, grey and white tie-dye grandad vest. It was too big - they weren't catering for kids my age - and hung off me, but I loved it.

Nothing wrong with pop.

It's just something internal that says, 'I've got to do this now. This is what I'm doing now.'

I want to hear as much music as I possibly can before I leave this mortal coil but it's impossible to hear it all because there's so much of it.
