Genie mentioned "Singing in the Bathtub" which is my Significant Other's (where DO they find these descriptions?!) favourite shower song - a la Robert Crumb and the Cheap Suit Seranaders. I believe there is a Mudcat thread that details that song's origins ...He also likes to practice his Tibetan Monk impersonations (he's actually very good at it!)
I remember the queueing for showers at Folk Festivals being made more bearable, by the impromptu community concerts from the shower stalls!! Cheers! R-J
