My childhood growing up in that part of Glasgow always sounds like some kind of sub-Catherine Cookson novel of earthy working-class immigrant life, which to some extent it was, but it wasn't really as colourful that.

What annoys me about it is that your fate is always in somebody else's hands. It's always up to somebody else to decide whether or not they want you in their show and so the majority of actors have to play out a waiting game. The constant fear is that it could all end tomorrow.

What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.

Listen to the Beatles' 'Things We Said Today.' Ringo Starr does not play a fill in the entire song. It doesn't need it. 'A Day In the Life' has gorgeous fills, but there, the song needs it. When I play on any record, I'm striving to get where Ringo is. You play what doesn't take you out of the song.
