One of the best piano players there ever was, but most only know him as a singer.
Truth. I've been listening to Nat King Cole since I was a kid, but only discovered he played the piano this past year. Felt pretty dumb about that, since I've seen plenty of pictures of him AT the piano, but I guess I'd assumed he was one of those guys who could play enough to accompany himself while practicing or something, not that he was really good at it.
