I felt that, in retrospect, there was a time in the late Seventies, after I had a string of hits and successes, as a performer and a recording artist, that I wasn't saying anything.

I'm not a jazz singer.

I am not a jazz singer. I wouldn't place myself on that footing. I wouldn't even enter that arena.

This is a cause that musicians can take to heart because one of our main reasons for being is to share our music with other people, and this takes us to people who probably wouldn't otherwise get to hear music on quite this level.
