No, not Charles or Harry, the talented one: Prince Rogers Nelson
Just finished Ronin Ro's Prince: Inside the Music and the Masks. I found the biography quite interesting. Having never been more than a causal fan of his music, there was a lot of fascinating (to me, anyway) information on Prince's history, music and personal life. Of course you could boil it down to:
Musical genius + hard work + borderline personality disorder +
a talent for being a dick = Prince
Not sure I'd want to go to dinner with the guy, but as a musician my admiration for his talent was certainly raised by this book. Recommended.
