I have this DVD and have enjoyed it many times ............ with Junior Wells, Sippie Wallace, Buddy Guy, Etta James, Albert King, John Mayall, John McVie, and Mick who is part of the "house" band that plays with all of them. Mayall on harmonica here

Bonus track from same DVD, Colin Allen on drums and he is a great studio guy who has played with Bob Dylan, John Lee Hooker, Sonny Boy Williamson, John Mayall's Bluesbreakers, and oddly enough '74 - '75 with Focus
