Never met him or collected his autograph but Harry was the very first concert I'd ever seen. He played over 2 1/2hrs with a full 70-80 piece orchestra as his 'backing band.' Incredible show. One of the best voices ever in recorded music.
It's a beautiful signature - I was in the hunt for a couple of examples in the last 12 months but failed to get either of them, One was alongside Martin Luther King's which is why I didn't get one.
