Australian cabaret artist Kim David Smith returns to Provincetown’s Post Office Cabaret with “Comme Une Folle — torch songs for tough times because gay.” Queer mega-muses collide in a conjuring of torch-singing, bruise-hearted ladies and their loungy lamentations; Marlene, Minnelli, and Minogue meet Eartha, Piaf, Judy, and more, in jazzy, Julie London-esque rearrangements by award-winning musical director Tracy Stark (piano).
