This is what YouTube is for: Gatemouth Brown on stage with Canned Heat at Montreux in 1973.
The Dark End of the Street was originally recorded in 1967 by R & B artist James Carr. This is Ry Cooder and band in 1977.
I don't know what the occasion for this performance was but they put a nice band together for it. This is Little Milton on a tune he originally recorded in the seventies called That's What Love Will Make You Do, with some help from Jimmie Vaughan. Have a good weekend.
