On June 6-8, 1968, The Mothers of Invention headlined shows at the Fillmore (first night) and Winterland (next two nights). The supporting acts were B.B. King and Booker T. and the M.G.'s. It's a good example of the kinds of diverse shows Bill Graham would put on in those days. The Mothers were experimental rock, King was blues, Booker and the M.G.'s were R&B. All are in the Rock and Roll Hall of Fame.
Jazz Casual was a TV show out of KQED in San Francisco that ran occasionally from 1960-1968, shown on NET (which later became PBS). The host was critic Ralph J. Gleason. A look at Gleason's guest list boggles the mind: Dizzy Gillespie, Dave Brubeck, Carmen McRae, Sonny Rollins, Louis Armstrong, John Coltrane, Mel Tormé, Count Basie, and many more. In May of 1968, the guest was B.B. King. It gives an example of what B.B.'s music was like at the time. The band is B.B. King (Guitar), Sonny Freeman (Drums), Jim Toney (Organ), Mose Thomas (Trumpet), and Lee Gatling (Saxophone).
