First time I saw him was opening for Robin Trower in 77, he pretty much played the whole Derringer Live album. Then with the J Geils Band where he had a guitar battle with Geils in which they tossed guitars to each other during the solos!
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.
