In I Am a Groupie a bored teenage girl named Sally wants to see the world, so naturally she hooks up with a passing rock band called Opal Butterfly—a real group from the late 1960s, by the way—and discovers that being a communal lay is harder work than she thought. The lead is played by Esme Johns, in her one and only cinematic role. Also known as Groupie Girl, this debuted in the U.S. in December of 1970.
Smalltown girl travels with band, smashes their guitars.
