Today in 1994, Passion opened at the Longacre Theatre, where it ran for 97 performances. Passion is a musical with music and lyrics by Stephen Sondheim and a book by James Lapine. The story was adapted from Ettore Scola's film Passione d'Amore. Passion is notable for being one of the few projects that Stephen Sondheim himself conceived, along with Sweeney Todd and Road Show. Set in 19th century Italy, the plot concerns a young soldier and the changes in him brought about by the obsessive love of Fosca, his Colonel's homely, ailing cousin.
