– You mentioned Jon Lord, but there’s another Jon you played with: YES’ Jon Anderson. For me, it’s something completely different.

You know, I always had this kind of very raw taste in music, and I can enjoy applying my style to lots different styles of music. I just do what I do – you said earlier yourself that it’s very difficult to pinpoint any specific style or specific influence in my playing, and I worried about that sometimes during my career. I always admired people like Steve Marriott that were really focused on a particular style and just did what they wanted. They seemed to have the calling to do one particular thing, and I kind of envied it. I’ve always liked to learn different styles, so I’ve never had a problem with switching from playing with something more jazz-influenced to something like Jon Anderson.

– Did you get to play with Anderson through Ian Wallace who drummed for THE WARRIORS, where Jon was a singer, and much later with HUMBLE PIE?

No, my connection with Jon Anderson was Ronnie Leahy, the keyboard player in STONE THE CROWS, who’s been a very dear friend of mine since late Seventies – and that’s how I got to know Jack Bruce as well: Ronnie introduced me to Jack – they’re both from Glasgow and had worked together in the line-up which included Mick Taylor. Ronnie was a good friend of Jon Anderson’s and a godfather to one of Jon’s children.
