Alex McMurray led the Tin Men and his oddly popular Valparaiso men’s chorus through a rousing set of sea shanties that was possibly the most high-energy of any set at the Bingo! Parlour all weekend. (Funny, how he can deliver a line like “Boston, the land of the bean and the cod” with such sweaty conviction.) This iteration of the choir included Bad Off frontman Erik Corriveaux, klezmer wizard Jonathan Freilich, Happy Talk Band leader Luke Allen, actor Chris Lane in white tie and tails and Gambit contributor David Kunian.
