Mamma Mia

We're not ready to forgive the folks who let Pierce Brosnan sing in the film, but a good antedote is the musical, "Mamma Mia!" which splashes into the Colonial Theatre tomorrow. The Broadway megahit created from ABBA tunes takes place on a Greek island where a bride-to-be invites three of her mother's former beaus to see which one should walk her down the aisle. -June Wulff, Globe Staff
