Prince had a song back in the 80's (a B-side, actually) that had Christmas in the title. And while the sombre mood of the song bears no resemblance to a party mood, it seems most appropriate to include a mention of it in our trivia challenge. So what was the name of the Prince B-side from the 80's that mentions Christmas in the title?

Bonus Question: Back in 1988, Bill Murray starred in a retelling of the familiar Christmas Carol story called "Scrooged." The big musical number at the end is a cover of "Put A Little Love In Your Heart," which is sung by Al Green and a famous star from the 80's (as well as the cast of the film). What's the name of the 80's popstar who duets with Al Green on this version of "Put A Little Love In Your Heart?"
