Amanda Stern's long-running and acclaimed reading/music series makes its debut at Joe's Pub tonight. The Happy Endings might have moved north of their former-brothel digs in Chinatown, but the evening should be just as saucy and rambunctious as ever, with contributions from the king of LES skeeze, Lush Life's Richard Price, and Nada Surf's Matthew Caws. Price is required (as all series readers are) to take one "public risk" over the course of the night, while Caws must bolster his two sets of original tunes with an audience-involving cover tune of his choice.
