FYI I believe she recorded 2 versions at the Xmas special. One for the special and the one in this video so watch the Xmas special to see the other performance!
I think we all figured that out already, didn't we? Like there are no kids in this vid, so there must be another performance in the Xmas special.
Honestly? Can another fave serve plain vocal as their promotion for an album? Other than Adole, comupter says no. (Plus, how many effortless G5s/G5#s does an Adole hit?)
