There's been a great deal of hoo-ha over the fact that Mick Jagger is hosting the season finale of "Saturday Night Live" next weekend, including this article in Billboard. Jagger sort-of hosted back in the first episode of the fourth season, in 1978, when the Rolling Stones were the (terrible) musical guest and there was no official host, although Jagger appeared in a few sketches.
But the relationship between Jagger and SNL producer Lorne Michaels goes back even further than that. Lorne Michaels has always been a man who knows which side of his toast has been buttered, and he was tight with Jagger before SNL was even on the air, at a time when Jagger was possibly the biggest star in the world. In the book Live From New York, writer and filmmaker Tom Schiller recalled this scene from the early days:
When I first arrived in New York, I slept on the couch in Lorne's apartment. He would entertain people like Mick Jagger at the apartment, and Jagger would be sitting on the very couch that I was going to sleep on. I just couldn't wait for him to leave, because the second he got up, I would go to sleep.
