Wikipedia on the Bags:
The Bags were an American rock band formed in 1977. They were one of the first generation of punk rock bands to emerge out of Los Angeles, California.
The Bags was formed by Alice Armandariz and Pat Morrison, who had met at an audition for Venus and the Razorblades, Kim Fowley's next attempt at creating a band after The Runaways had left him. Armandariz and Morrison decided to form their own band and from this The Bags were born. They took the band's name and their stage names "Alice Bag" and "Pat Bag" from a gimmick that the band used during early performances where they would perform with grocery bags over their heads (the practice did not last, in part due to an incident where Darby Crash of The Germs ran up on stage and ripped the bag off Alice's head). Alice Bag was the vocalist and Pat Bag played bass. The band was rounded out by guitar players Craig Lee and Rob Ritter, and Terry Graham played drums.
