"Celebrate the Season"
"Silent Night"
She has a speaking role in the beginning, then they sing the first verse in German and then English for the 2nd verse.
" 'Gonna Catch That Santa"
Santa appears at the end
"One Candle"
It takes a while for them to start lighting "candles" (aka flashlights) so it is dark in the beginning. This is the one she does sign language in.
