According to Gizmodo on Dec. 7, an amusing and festive compilation of "Star Trek" clips are pieced together intricately to form a song parody of "Let It Snow!" song. The tune is entitled "Make It So!"
It appears that most of the clips are of Patrick Stewart singing the rendition most of which were specifically from "Star Trek: The Next Generation" TV show. Also, Commander Data, Worf, and Commander Riker pitch in to contribute to the Christmas shenanigans of the re-imagined science fiction version of such a Christmas carol.
While some carolers would be singing the traditional song from house to house during the holidays, this one could be specifically presented at conventions all over.
Keep in mind as the video clip ends there is a game developer promoting his new game called "Blackwhite". So if you do not want to sit through the entire commercial, there is also an edited version of the clip on YouTube.
