Queen Elizabeth Hall, SE1 (0171-960 4242) 7.45pm "I am Country Joe. I don't pretend to be Country Joe. I don't have a Country Joe suit in my closet." Thus spake Country Joe McDonald - the West Coast folk-singer whom many identify as one of the truly gen-u-ine voices of Sixties protest. His appearance at Woodstock is the stuff of legend - as if his anti-Vietnam singalong "I Feel Like I'm Fixin' to Die Rag" wasn't rousing enough, the crowd substituted the four letters of his introductory chant ("F, I, S, H") with ones that sent a chorus of disapproval to the Nixon administration in a language the president himself could understand. But McDonald has not been resting on past hipness. This rare appearance, timed to coincide with the rerelease of his soundtrack to Quiet Days in Clichy - Jens Jorgen Thorsen's frisky 1969 adaptation of Henry Miller - is part of a working holiday. He's over here researching the life of one of his favourite people, Florence Nightingale. Weird, huh?
