Your characters got roped into doing Christmas (or relevant winter-solstice-adjacent holiday) karaoke! What do they sing? Here are some examples:
Naomi and CJ duet "Fairytale of New York." This is not the first time they've done just that; as a result, they absolutely crush it.
Brandee sings "Drive The Cold Winter Away." She found a metal cover and translated it into Spanish and Mandarin.
Kieron decided to tackle "Rebel Jesus." He had to psych himself up beforehand, tripped over the words a little at one point, and was brick-red for the remainder of the song.
Talula found something composed by voluntarily and exuberantly syncretist xenosophonts that translated to something humans could enjoy, and presented that. Alternately: they were a total troll and covered "I Don't Know What Christmas Is," complete with the spinning-arm bit because her prosthesis can do that.
Okay; your turn!
