Emmy winner Meredith Vieira is no stranger to TV, but it wasn’t until earlier this fall that she made her first splash on a Broadway stage for a special appearence in Disney’s Mary Poppins. Vieira joined the Mary Poppins company at the New Amsterdam Theatre to make a brief cameo as a chimney sweep during the long-running musical's showstopping number "Step in Time." Current Mary Poppins stars Steffanie Leigh and Gavin Lee then reunited with Vieira when they appeared as the first contestants on Who Wants To Be a Millionaire’s “Broadway Giveaway Week.” Leigh and Lee won more than $20,000 for the Actors Fund on the popular ABC game show. Check out Vieira's adventure at Mary Poppins below.
