A festival at San Francisco’s Theatre Rhinoceros presents a series of short plays with gay or queer themes from the entire span of the 20th century – from a 1907 Russian “mini-musical” through Tennessee Williams and Joe Orton to a Tony Kushner one-act from 1998. The selection “poses some fascinating then-and-now questions about how gay life is seen in a culture that keeps rotating the lens to sharpen the view, blur it or blot it out altogether.”
