Flight of the Conchords seem to parody themselves plenty when they label themselves New Zealand’s 2nd most popular comedy folk duo. After a floundering BBC radio and an HBO comedy series, and their eponymous album with this bizzy song (released as downloadable content for the video game Rock Band), Jemaine Clement, Bret McKenzie, and Rhys Darby went their separate ways. But Tom Wade and The Parliament had the same idea: switch out the word business (meaning SEX in the original song) with the assonant Christmas. So now it’s “Christmas Time,” ladies and not-ladies.
