Look I don't know his music as they don't play it on the oldies station . I think he's probably surrounded by yes people and has only know success so is probably incredibly arrogant.
However... It does appear he does some fantastic work with the make a wish foundation etc. When you're as busy as him and he still takes the time to give back... Well he can't be all bad.
I don't think there's a way for anyone to be in that environment and not be arrogant.
