I've always been fascinated by the Norsemen, their lives, history and cosmology. The more we study them the more interesting they become... breaking their own stereotypes. We usually think of them as barbarians, but there were aspects to their society that shows a tremendous level of civilization, sophistication and social advance.

The '50s in general are written off as a boring decade following the turmoil of the Second World War and its immediate aftermath - the postwar Labour government, the cold war, the arrival of the New Look in fashion, etc. But I remember it as a very exciting time - a pioneering, rule-breaking time, especially for the young.

If you're in pop music, you've got to deal with the changing of the guard every few years. By the time the '70s arrived, I was well aware of the cyclical nature of the game. Pop music is a creature of the moment; it thrives on the mood of its time. Either you hook into that or you're not going to be part of it.
