Paul Anka

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.

Once you realize that you're in something that you've always wanted and you don't want to lose it, you behave differently. And that means the integrity, the professionalism, and knowing what's right from wrong and still making choices that you probably wouldn't have made.
