'The Sound of Music Live !," NBC's unexpected little stocking stuffer to itself, will get a curtain call on Saturday, from 8 to 11 p.m.

Last Thursday's three-hour telecast was watched by 18.6 million viewers who marveled at Carrie Underwood's thespian skills, but that number grew to 21.3 million when NBC factored in the so-called live-plus-three figure, which included those who watched via DVR. So the news gets better for the network. NBC had planned to air "It's a Wonderful Life," but that will now be telecast on Friday, Dec. 20.
