When I was a teenager, I really didn't like loud rock music. I listened to jazz and blues and folk music. I've always preferred acoustic music. And it was only, I suppose, by the time Jethro Tull was getting underway that we did let the music begin to have a harder edge, in particular with the electric guitar being alongside the flute.

In writing lyrics - well, for me, anyway - it's about getting into character, you know? 'Who is writing this?' In the case of the original 'Thick As A Brick,' supposedly a precocious, very young child who's fantasizing about his future and the context of all the confusing elements to which school boys are subjected at that time.

It might work with one orchestra, and the next orchestra - the oboe player might not get it. It's different every time, but some of the orchestras do end up enjoying it and having a great time.

I was quite keen on silviculture, the growing of trees, and that was something I gave a lot of thought to. Maybe I could've gone in that direction. But it just so happened that while I was trying to make up my mind, I enrolled in art school, and there I began to develop my interest in music, parallel with my interest in the visual arts.

There seems to be an inclination among rock musicians to be very carefree with money, but I negotiate the best flight and hotel deals on our tours to maximise the band's income - I don't want too see too much taken off the top line.

All the time I was playing the flute, the lines, the solos, the riffs, the construction, were based on my guitar skills. I did not play the flute to exploit its natural faculties, but I used it as a surrogate guitar.

As a songwriter, you tend to develop your own style, your own technique, based around what it is you're trying to write and perform, in terms of your own music. So a way of evolving a guitar style as a songwriter is much easier, I think, than developing a true style of your own just from listening to music or playing other people's music.
