No, they don't.
I saw the film yesterday, yes, just for Benny Golson, and sure enough, he's only on screen for about one minute. The rest of the movie wasn't horrible, but certainly wasn't worth $9.50. In the flick, Hank's character, Victor Navorsky, explains that his father was the one who was impressed by the Esquire photo, and who then started patiently collecting the signature of every figure in the picture. He died before securing Golson's signature, so Victor (Hanks) tries to get it as a sentimental tribute to his father. Jazz as sentimental macguffin. Still, when the deskman at the hotel said, "Are you a jazz fan?" that kinda got me (sniff) right here. (Excuse me...I'm a little yclempt...)
