As Marvin struggles to create a “tight knit family” out of his eclectic array of core relationships (including his ex-wife, his new boyfriend, his adolescent son, his psychiatrist, and his neighbors) amidst a series of monumental life changes, he is forced to reckon with his own views on love, responsibility, and what it means to be a man.

Following productions of one-acts "In Trousers" (1979) "March of the Falsettos" (1981) and "Falsettoland" (1990) at Playwrights Horizons, "Falsettos" was created utilizing the latter two, forming a two-act musical. "Falsettos" opened on Broadway in 1992 at the John Golden under the auspices of Barry & Fran Weissler. James Lapine directed a cast which included Stephen Bogardus, Michael Rupert, Chip Zien, Carolee Carmello, Jonathan Kaplan, Heather MacRae, and Barbara Walsh.
