Hi -
First, I'm not associated with this site in any way - I just wanted to point out that there are some very interesting photos viewable at: www.popsiephotos.com. They are the work of the late Popsie Randolph. Highlights of the jazz section include Bird sitting in on tenor with Lionel Hampton as well as Lester Young and Max Roach chatting at the 1953 Metronome All-Stars session.
There are two photos listed under Lips Page - the second one's caption identifies Buck Clayton, but I'm curious if anyone else agrees with me that the photo also includes Leo Parker, Shadow Wilson and Paul Gonsalves.
Enjoy.
