The cast of "The Avengers" and "Guardians of the Galaxy" must have been too busy to get together and record a legit holiday album, which is a shame, but this Christmas musical mashup using bits and pieces from their movies is almost as good! Thanks to video editor and YouTuber James Covenant, it turns out that Tony Stark and friends can do a very passable rendition of "We Wish You a Merry Christmas."

Just set the mood with a glass of egg-nog, string up some twinkle lights, and let the Avengers serenade you. Also, be sure to stick around for the all-Groot rendition of "Jingle Bells."
