Orbach would go on to become an accomplished Broadway and off-Broadway actor. His first major role was El Gallo in the original 1960 cast of the decades-running hit "The Fantasticks," and Orbach became the first to perform the show's signature song and pop standard "Try To Remember". He also starred in "The Threepenny Opera"; "Carnival!", the musical version of the movie "Lili" (his Broadway debut); in a revival of "Guys and Dolls" (as Sky Masterson, receiving a Tony Award nomination for Best Featured Actor in a Musical); "Promises, Promises" (as Chuck Baxter, winning a Tony Award for Best Actor in a Musical); the original productions of "Chicago" (as Billy Flynn, receiving another Tony Award nomination); "42nd Street"; and a revival of "The Cradle Will Rock". Orbach made occasional film and TV appearances into the 1970s and appeared as a celebrity panelist on both "What's My Line?" and "Super Password".
