I met Roy at a show in a small club in Boston before his death. A drummer friend [ Dan brubeck] was doing a gig with him and I went along for the ride.
The Room was Johnathan Swifts and the placed was packed with nothing but guitar guys.. they went nuttzzzz when he wailed..unreal player. Literally tore the House Down !!!!

Another Hammond jazz lady was Shirly Scott, but my Fav is still Jimmy Smith.
Back at the Chicken Shack and Who's Afraid of Virginia Wolf. I met him in the mid '60s in DC . He got on the POP scene with Mojo Workin' ..
Other that were hip back then were Jack McDuff and Jimmy Mc Griff..

..and we all remember Billy Preston....and almost forgot , Groove Holmes.
