The subjects of Stephen Sondheim's musicals are almost always surprising. One example would be the fairy tale setting of Into the Woods (1987) which gradually transforms into a story of modern family life. And then there's Assassins (1990), which is as disturbing as its title. Sunday in the Park with George (1984), about the pointillist painter Georges Seurat, must be considered among the most unlikely concepts to make it to Broadway, although Sweeney Todd (1979) would surely be in the running. Company (1970) however, at first anyway, doesn't seem unusual in this regard, but after seeing it we realize that its subject matter is daring as well, because it's about the psychological complexity and essential loneliness of upper middle class people, the very people that are in the audience. Here's the opening to a version starring the great Broadway actor Raul Esparza, with its title song that is pure Sondheim: http://www.youtube.com/watch?v=JJsd_Cvk_rw
