If you just can’t wait for the transatlantic transfer of the hit West End Cabaret that was recently announced, cheer up, there’s another Nazi musical in town. That would be Chanteuse, the bleak and arresting solo tale of the remarkable fate of one gay man in Weimar and post-Weimar Germany. The performer, Alan Palmer, also wrote the book and lyrics, while the curiously soothing music is by David Legg. Chanteuse has a frightening and touching story to tell, but you might not be entirely on board with the way it gets told.
