When you've done something, certainly if you create a piece of music, you then hear it with fresh ears when you play it for somebody else.

You can draw a line between what I'm interested in and what I'm not interested in. On one side you can name Dylan and Lennon, who observe the world and have feelings, and write songs directly from those feelings. On the vapid side you have pop groups who need material and write songs to fill the hole, rather than getting somebody else.

Part of the reason I'm doing Us + Them tour is to play my part in trying to spread the message that cooperation is a better way to resolve conflicts than confrontation. That bridges are better than walls, that nationalism and exceptionalism is destroying our world and destroying our lives.

That one record changed everything for me. After Sgt. Pepper, it's the most influential record in the history of rock and roll. It affected Pink Floyd deeply, deeply, deeply. Philosophically, other albums may have been more important, like Lennon's first solo album. But sonically, the way the record's constructed, I think Music from Big Pink is fundamental to everything that happened after it.

It's a miracle was the last track recorded for the album, we based it on the rhythm from the middle of 'Late Home Tonight, where there's Graham Broad playing lots and lots of drums with me shouting in the background, pretending to be a mad Arab leader.

In my rear view mirror the sun is going down sinking behind bridges in the road and I think of all the good things that we have left undone and I suffer premonitions confirm suspicions of the holocaust to come.

By the cold and religious we were taken in hand - shown how to feel good; and told to feel bad.
