Excellent show man! Saw winter a number of times. He never disappointed. Saw him in 1979 in central park wollman rink. Same year an absolute honor to see muddy waters at a small venue called my father's place in Roslyn long island with special surprise guest johnny winter. The place went frantic! Pure memory burn! A bit of music trivia for you. Yes Derringer wrote rock and roll hoochie Koo. But winter recorded it when Derringer was in johnny winter and group first. But of course Derringer made it a smash hit from his solo album. Rip johnny but the rock and roll and blues will never die!
