Unknown garage band playing their only known song in this sexploitation feature! Members were Tom Lotila, Emil Papa, Tony Conocenti and Bob Sutton. I believe the film was made in New York, so they must have been from the area. More info will be appreciated!
The club is apparently named "The Grotto Au Go-Go" owned by Mr. Pogio.
The movie is "Mini-Skirt Love" (1967) directed by Lou Campa and starring Janet Banzet.
Warning: The movie is rather disturbing otherwise, don't feel obligated to search for it.
