Happy Mamma's Day! Watch Judy McLane & the Cast of Mamma Mia! Dance & Jive at 30 Rock

Friday night and the clouds are low...but that's not stopping them! The Today Show concluded this week’s “Best of Broadway” series with a bouncy and spandex-laden performance from the cast of Mamma Mia!. The colorful crew pumped up 30 Rock crowds with their rendition of the title song and “Dancing Queen.” What better way to celebrate Mother’s Day than with the spunky Donna Sheridan (currently played by Judy McLane)? She may have dropped the ball on the whole baby daddy subject, but any mom who will sing ABBA tunes with you is a great mom. So go ahead, have a look, wave your arms in the air at your desk (we won’t judge) and happy Mother’s Day!
