The Grateful Dead performed Cream Puff War on one edition of this Bay Area music program in 1967. It's possible that part of Walkin' Blues performed by the Dead was also broadcast but this has not been confirmed. The music was recorded at the KPIX-TV Studios in San Francisco on April 8, 1967. The program also included an interview with Jerry Garcia, Bob Weir and Phil Lesh and music from Quicksilver Messenger Service and The Wildflower.
It's possible that the Grateful Dead featured on other episodes of The Maze.
