This Saturday marked the last time we’ll see Kristen Wiig on the Saturday Night Live stage as a cast member of the long-running sketch comedy show, but it wasn’t the episode that has people talking days after it happened– It was the after party.

After Andy Samberg and Kristen Wiigs final curtain call early Sunday morning, the cast, crew, and friends of the show headed out to 30 Rock’s outdoor plaza to have what seemed to be the best party you’ve never been to (but don’t get too sad– we weren’t there, either).

After the tearful goodbye to two fan favorites, the official after party kicked off outside the NBC studios, and it was beyond amazing. Not only were former SNL favorites Amy Poehler, Chris Kattan and Rachel Dratch on hand to give Wiig and Samberg their final goodbye, some of rock’s finest took the stage to send them off.

Jeff Beck, Arcade Fire, The Foo Fighters and Mick Jagger himself all stayed around to play a live set during the after party, which insiders say went from laughter-filled to bawling-your-eyes-out sad throughout the night.
