Stephen Sondheim’s Company is a uniquely adult musical about marriage, and this touring production of last year’s Broadway hit gender swaps the lead, Bobbie, and takes a revelatory modern take on an already groundbreaking show. With classics like “Ladies Who Lunch” (remember the pandemic Zoom version with Meryl Streep?), “Being Alive” and of course the fast-talking “Getting Married Today,” Sondheim fans and newcomers alike will love it.
