Last year, TheaterMania celebrated Mother's Day with a video of Liza Minnelli and her mom, Judy Garland, belting Broadway's best mother-daughter duet, Gypsy's "Together (Wherever We Go)." This year, we're sticking with the most adorable mother and daughter show biz has to offer. In this video, they're slightly older and performing in their show Judy Garland and Liza Minnelli "Live" at the London Palladium. Clearly, like any good mother and daughter, they've gotten their duo act down to a T, delivering a fantastic arrangement of "Get Happy/Happy Days" in delightfully mismatched blouses.
