Billy Joel is probably my all time favorite piano man. Elton John is a close second for his music only.
I think what turned me off some was when I seen a show on cable where a camera man was following Elton John around behind the scenes and he was throwing tantrums like a little baby and yelling at people over trivial stuff...I'm sure there are others who have a different "persona" off stage too. I'm told Ellen degeneres is a spitfire off stage, been known to roll heads.
We all have a bad day, but this was over and above that. Elton still plays great music. Can't take that away from him.
