‘Mamma Mia,’ what a show!

The famed pop-musical Mamma Mia! comes to the River Center this month, bringing the bouncy music of 70s dancehall sensation ABBA to service a romantic comedy story of a bride-to-be searching for her biological father. On the verge of walking down the aisle, Sophie Sherridan writes letters to three men who she suspects may be her real dad—but when all three show up on the eve of the wedding, Sophie and her mother and grandmother are suddenly faced with generations of family secrets. Friday and Saturday. Visit brrivercenter.com for full schedule and tickets.
