Leave it to Encores! to attract Broadway’s best talent to their productions of seldom-seen musicals: For Pipe Dream, a 1955 tuner from Rodgers & Hammerstein, the grade-A cast includes Laura Osnes and Will Chase as would-be lovers Suzy and Doc, plus Cannery Row residents played by Tom Wopat, Leslie Uggams (as a madam!) and Stephen Wallem. Theatrical photographer Joan Marcus shot portraits of these talented headliners before rehearsal for the show, which will play seven performances at New York City Center, March 28-April 1. With a cast like this, how can Pipe Dream miss?
