Someone need to sing-along?

I’m just finishing up a pile of sing-along Christmas pieces for a stage production. Being seasonal, I decided to get them out as soon as possible.
Super-peppy sing-alongs! Right now, they are the first four pieces on this page. “Up on a Housetop”, “Jingle Bells”, “Deck the Halls”, and “Oh, Christmas Tree”.
Cheers, everyone!
