We all know that, every year, Trekkies gather around the yule log to hear Captain Picard sing "Let It Snow." But they also enjoy other traditional Trekmas carols remixed by John C. Worsley, such as "Enterprise Rock", a take on Bobby Helms's "Jingle Bell Rock" by the crew of the Enterprise NX-01 . . .
. . . "Wonderful Deep Space Nine," inspired by Paul McCartney's "Wonderful Christmas Time" . . .
. . . and "Happy Trekmas," which is Worsley's take on John Lennon's "So This Is Christmas."
For those who can't sing, there is the instrumental (or instrument panel) version of "Jingle Bells."
