Everyone who was anyone was at the 40th anniversary special of Saturday Night Live last night (which bizarrely was on a Sunday but maybe they just wanted to keep everyone on their toes), with past stars, guest hosts and musical guests alike all thronging the stage over the three and a half hour broadcast.

With appearances from Steve Martin, Bill Murray, Will Ferrell, Tina Fey as well as Paul McCartney, Kanye West, Miley Cyrus and Taylor Swift on top of the return of characters and sketches from years gone by, it was a jam-packed affair and we'll bring you more of it as the day progresses (including Bradley Cooper wearing the face off Betty White, Taylor Swift doing an incomprehensible Californian accent and even more celebs in one room than the gift bag area at the Oscars), but for now enjoy Jimmy Fallon and Justin Timberlake's musical intro to SNL40and see if you get all the references.
