I saw him and his partner play many, many times during my youth. My aunt dearly loved them, had many of their albums, and when my uncle didn't want to se them yet again, I'd be selected to go. Of course, I enjoyed them very much, too, so I always looked forward to seeing them again.
She also had the same kind of crush on Leonard Bernstein (join the club), and we went to see him every time he came to town, too.
