This one hits hard, used to see R.D. with Edgar Winters White Trash about every 3 weeks or so @ Signorelli's Night Club, aka Slicks, in St. Martinville Louisiana and every now and then Johnny would show up with them. This was around 1970, about the time Johnny was catching on with his music and White trashes lead singer was Jerry Lacroix one of the best blue eyed soul singers around. I can still feel that dance floor shaking as they got after Ray Charles I got news for you, and my girl friend telling me that the slow gin sizzles wasn't going to get it just get the Wild Turkey setup. RIP
Rick Derringer R.I.P
Unfortunately, another major 70’s guitar player checked in for "The Great Gig in the Sky."
Rick Derringer was one of those unique "did everything with everyone " musicians.
