The Rendezvous Club was located in the basement of the Douglass Hotel.
In a May 11, 1959 conversation with celebrated jazz journalist Ralph J. Gleason, trumpeter Dizzy Gillespie shared an anecdote:
… in Philly, I had an interesting experience with Roy [Eldridge]. All the bands used to come to Philly. When I got to Philly in ’35, Roy was with Teddy Hill and Chu [Berry], and they used to jam downstairs in the Rendezvous up under the Douglas Hotel where the Showboat is now. Well, those guys used to play and I wouldn’t dare play, you know. I’d just go and listen to those guys. So one time, I remember, Rex Stewart, Duke Ellington, and Teddy Hill were there at the same time and they had a session downstairs and Roy was down there that night. And Rex, you know, Rex was Roy’s idol. Roy tells now about the time he first heard Rex play that high B flat. Roy finally found that B flat. I guess, ‘cause when he come to Philadelphia that night they was jammin’ round there and Roy started playing. Damn, Rex started crying and just tightened up and left ‘cause Roy was in rare form that night. I didn’t meet Roy until way later. I met him there, but he didn’t remember me.
