The performance was on 26 July 1969. A less than sunny Saturday afternoon at State Fair Park in West Allis, Wisconsin. The happening was promoted as "The Rock & Roll Festival". Opening acts were local, followed by another British group called Taste (with Rory Gallagher), then by the Motor City (MC) 5, John Mayall, and Delaney, Bonnie & Friends. Prime time in the late afternoon was the new super group from England, Blind Faith...........
