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.'

In a way, I'm kind of a bystander looking at this phenomenon that is ABBA, which is still around, and that I thought would be finished in 1981 and forgotten. I'm amazed how this could happen, and I don't know why it happened. I'm just grateful and humble. I just sit back and enjoy.
