Yale has a passion for Stephen Sondheim in the last year. First came “Assassins” at Yale Rep last March; now comes a Yale Drama School version of the sexy “Passion.”

The one-act musical, with book by James Lapine, is known as one of the musicals that Sondheim conceived; the story was adapted from Ettore Scola’s film “Passione d’Amore” (in turn adapted from the novel “Fosca” by Iginio Ugo Tarchetti).

Rory Pelsue will direct graduate drama students at the University Theater production on York Street. Aside from sex, there are themes of obsession, illness, passion and power.

The setting, says a YSD release: “On a remote military outpost in 19th century Italy, a handsome soldier is relentlessly pursued by an anguished, ardent young woman, driving him to extremes of rage and ecstasy he never knew possible. Passion is a gothic fever-dream of a musical...”

The show was on Broadway from May 1994 until January 1995; it also had international runs and an off-Broadway revival in 2013.

University Theater, 222 York St., New Haven. Saturday, Feb. 3-Friday, Feb. 9 except Sunday, 8 p.m. $25, $10 students. 203-432-1234
