Butch Whacks and the Glass Packs was started in 1971 as a way for a bunch of St. Mary's undergrads to impress girls. That didn't happen, but somehow the band went on to open for the likes of Tower of Power, Boz Scaggs, the Doobie Brothers and Ike and Tina Turner before breaking up in 1976. The Glass Packs got together for a one-time reunion in 1983. They sold out three nights, they decided to do it again and then again... and now their annual farewell performance has become one of most anticipated weekends of the San Francisco summer entertainment scene. No one has delivered more laughs per minute than the Glass Packs who will be putting on their 31st annual farewell show this June.
