Company is a musical with music and lyrics by Stephen Sondheim and book by George Furth. The original 1970 production was nominated for a record-setting 14 Tony Awards, winning six. Company was among the first book musicals to deal with contemporary dating, marriage, and divorce, and is a notable example of a concept musical lacking a linear plot. In a series of vignettes, Company follows bachelor Bobby interacting with his married friends, who throw a party for his 35th birthday.
