[SNL's season 37 ended on a high note, with strong musical performances and an impressive comic turn by Mick Jagger, and a moving send-off for Kristin Wiig (in which Jagger and Arcade Fire performed "She's a Rainbow" and "Ruby Tuesday" while a teary-eyed Wiig danced with each castmember in turn). Andy Samberg and Jason Sudeikis are also rumored to be leaving, but producer Lorne Michaels has indicated that no decisions have yet been made. The episode showcased such recurring Wiig characters as the weird singing sister from the Finger Lakes and stage diva and perpetual Secret Word loser Mindy Elise Grayson. Mick Jagger portrayed everyone from a loony Steven Tyler to a J.P. Morgan executive, a blasé Californian, and a lonely insurance salesman. Jon Hamm and Steve Martin made cameos, and former castmembers Amy Poehler, Rachel Dratch, and Chris Kattan showed up to pay tribute to Wiig. Mick Jagger performed "The Last Time" with Arcade Fire, "19th Nervous Breakdown," and "It's Only Rock 'n Roll (But I Like It)" with Foo Fighters, and an election-inspired blues song with Jeff Beck.]
