Sometimes famous musicians get tired of being defined only by the music they do.
NOT famous musicians get tired of that too. I recall one specific incident where I was chitting and chatting with a girl in a bar. Just talking about stuff in general. I mentioned that I was a veteran. Later that I am a very good cook. Still later that I am a capable woodworker. Finally I mentioned that I played keyboards in the Motown band I was in. ONLY THEN did she show any reaction, saying "Oh wow! You're in a BAAAAAAAAAnd???"
Of ALL the things I have done in my life... Man, it's ONE thing I know how to do. That gets annoying.
