Musicals in Mufti: Saturday Night

The York's Musicals in Mufti, a series of stripped-down concert stagings of Broadway rarities, celebrates its 100th production with a rare look at Stephen Sondheim's unproduced-at-the-time 1955 musical comedy (with a book by Julius and Philip Epstein). The cast includes Margo Seibert, Lindsay Mendez, Andrew Keenan-Bolger, Ben Fankhauser and Jim Stanek; longtime Sondheim collaborator Paul Gemignani serves as musical director.
