Venue unsure, maybe Sam Houston Coliseum. David Swartz has a handbill that shows this as Hofheinz Pavillion, University of Houston, Houston, TX. Joe McMichael and "Irish" Jack Lyons confirmed David ("The Who Concert File", p. 103). This uncomplete set list was sent in by Rob. Clint Fletcher explains the venue: "Hofheinz Pavilion is now called Fertitta Center, see https://en.wikipedia.org/wiki/Fertitta_Center. It is an arena on the University of Houston campus - home of the Houston Cougars (aka Phi Slamma Jamma). Not to be confused with the Sam Houston Coliseum which was demolished in 1998."
