On Friday, October 22, the current cast of Broadway's Mamma Mia! celebrated the lighting of two brand new disco balls that have been installed on the Winter Garden Theatre marquee.

On hand for the event were stars Lisa Brescia, Judy McLane, Gina Ferrall, Liana Hunt, Corey Greenan, Clarke Thorell, John Dossett, and Patrick Boll.

The musical uses the songs of ABBA. It follows the story of a forty-something mother planning her daughter's wedding -- unaware that the girl has invited three men who might be her father.
