Scrapping the usual comedy skit to open the show, this week's episode of Saturday Night Live opened with a tribute to the 20 children and six staff members killed by a gunman in Newtown, Connecticut on Friday. Instead of the typical political satire or humorous take on current events, the New York City Children's Chorus sang a very somber rendition of "Silent Night".

After the song the children's choir shouted the show's standard opening, "Live from New York, it's Saturday Night!"

The show was hosted by SNL alum Martin Short and featured musical performances from Paul McCartney.

The final episode of the show this year also featured special guests Tom Hanks, Alec Baldwin and Samuel L. Jackson; the latter of whom allegedly swore during a skit on live TV.

During a cameo with regular Kenan Thompson, Jackson allegedly said the "F" word, followed by "bulls--t"; after which Thomspon called him out, saying, "Come on, Sam... that costs us money."

Jackson denies the gaffe though -- well, part of it. He tried to clear things up in a tweet after the show; saying, "I only said FUH not F&*K! K (Kenan) was sposed (supposed) to cut off da BULL%^&T, blew it!!"

The Children's Chorus returned later in the show also, backing up McCartney during his song "Wonderful Christmastime". McCartney also played "Cut Me Some Slack" -- the new song he wrote with the surviving members of Nirvana and debuted earlier this week during the 12-12-12 Concert for Hurricane Sandy relief.

The song will be included on the soundtrack to Dave Grohl's documentary about Sound City Studios.

Eagle Joe Walsh joined the former Beatle during his sets.

"Sleep in heavenly peace" took on a whole new meaning during the opening, and if you don't get teary-eyed from the video below, they it's probably a good bet you have no soul...
