At the bash, held at the Plaza Hotel in New York City (that's the one from Home Alone 2) on Sunday night, Kim Kardashian, showing cleavage in a daring black gown with a plunging neckline, hung out with cast members. and earlier shared a backstage photo of hubby Kanye West, who had performed on the special, with Mike Myers and Dana Carvey dressed as their iconic Wayne's World characters (watch their sketch).
Taylor Swift grabbed a guitar and sang her 2014 hit "Shake it Off" and the Beatles' 1963 song "I Saw Her Standing There" with none other than Sir Paul McCartney, who had performed on the special as well.
They were joined on stage by show alum and The Tonight Show host Jimmy Fallon, as well as Jim Belushi and Dan Aykroyd, who had reprised their roles as the Blues Brothers on the 40th Anniversary show.

? Leslie Jones (@Lesdoggg) February 16, 2015At 4:30 a.m., many guests were still partying on! The stars seen inside the bash at that time included Murray and current cast members Aidy Bryant, Cecily Strong and McKinnon.
Of course, it's never a real party without a photobomb; Here is SNL alum and comedian Jeff Richards, who played "Drunk Girl" on the Weekend Update segment in the early '00s, and Murray being photobombed, as seen on his Twitter page.
And while the show, sadly, did not feature a full 'N Sync reunion, as many had expected, there was this reunion:
Here is Richards reunited with his pal Fallon (or, "Jimmy Ffffallon...").
