Bjorn Ulvaeus

It could be seen as narcissistic to have your own museum, but for me, it's such a long time ago - I have perspective. That young man in the funny clothes - he's almost a stranger, so I can tell his story.

Mostly, in song writing, my experience is that there isn't so much inspiration as hard work. You sit there for hours, days and weeks with a guitar and piano until something good comes. But the urge to write is something you have to have. A conviction, an ambition to write and never stop until you think, 'This is the best I can do.'

Because of my Asian-ness, I couldn't be anonymous - what I said, what I ate, what I did at the weekend were startlingly different to what everyone else did. I was also a performer, quick and chameleon-like, good at accents, so that made me stand out.

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.
