There are at least three bands named Calamity Jane. 1. Calamity Jane formed around 1988 in Olympia, WA. The band originally consisted of Lisa Koenig on drums, Ronna Era on bass and Gilly Ann Hanner doing vocals and guitar. The band played under different monikers, such as 'Catbox' and 'Sometimes Why'. Era left the band to form Treehouse and was replaced with Hanner's sister Megan. The band stuck with Calamity Jane for unknown reasons.
