@n80, God I love Little Walter! I have a copy of the Chess LP containing "Hate To See You Go", haven’t heard The Stones version. There’s a really good harp player living in San Jose by the name of Gary Smith whose album Up The Line (CD only) is super fine; I highly recommend it. Gary is very much influenced by Walter (as is Charlie Musselwhite, a mentor of Gary’s).
Gary and I were in a band together in ’69, right after he switched over from drums. He’s been at it for 50 years now, and has gotten REALLY good. He plays around the Bay Area, and a has good little band the locals refer to as The Blues Mafia. Its members include a real good piano player by the name of Sid Morris, with whom I last gigged in ’08. Gary and Sid shared the stage at the very first San Francisco Blues Festival, in 1973!
