Named after a track on Frank Zappa’s 1969 Hot Rats album, Peaches en Regalia was the brainchild of Berkeley playwright Steve Lyons, who began writing the comedy because he wanted to see actors boogey on stage to his favorite childhood song. After he attached a one-act to his lightning bolt of theatrical inspiration, it was performed in San Francisco, New York, LA, London, and Edinburgh. 

Renovating the original one-act and expanding it into a full-length play, Lyons' new version premieres at Stage Werx this month. Peaches en Regalia is as “unhinged, quirk-laden and weirdly benevolent as the original Zappa tune,” says The San Francisco Chronicle. Set in Doug’s Diner, a charming waitress named Peaches wrangles complex theories about gas prices, Norm wages battle with time management, and the jovial Syd plops down to solve everyone’s problems.

Through August 27. Stage Werx, 533 Sutter Street. Tickets are $24 at wilywestproductions.com. (Or $12 at the TIX Booth in Union Square.)
