Torn Ticket II, the only student-run musical theater group at Tufts University, presents the second of two performances of “Company,” its spring workshop show. In a series of vignettes, “Company” follows bachelor Bobby interacting with his married friends, who throw a party for his 35th birthday. With bountiful music and lyrics by Stephen Sondheim and an introspective script written by George Furth, 14 actors take to the stage to put on this cynically insightful musical about marriage and commitment. Tickets for the general public are $20; order through the Tufts online box office.
