Cast members from the National Touring cast of Mamma Mia! will perform All I Want For Christmas at Boston's Club Café on December 21 at 11pm. This holiday-time cabaret will benefit Broadway Cares/Equity Fights AIDS.

The event will showcase many of the cast as they perform seasonal favorites and other tunes. The benefit coincides with the return of Mamma Mia! to Boston's Colonial Theatre, where it will run December 15-27.

Tickets for the cabaret will be available at the door for a $10 suggested donation.
