Though Mick Jagger has been a musical guest on "Saturday Night Live" twice before, the show's creator said Monday the timing "felt right" to invite the Rolling Stones frontman to host.

"I know him pretty well, and I think he'll be charming and funny, and I think people will see a side of him that they're not used to seeing," the show's executive producer Lorne Michaels told the New York Post.

Jagger will be hosting the upcoming episode on Saturday, the season 37 finale.

"He's a very, very smart guy, and he's very, very smart about how to put on a show," he continued.

Michaels said he did not pursue the singer to host until recently.

"It felt right now," on the band's 50th anniversary, Michaels added.

The two men met in 1978 when the band first appeared on the program but kept up a relationship outside their main show-business interests.

They produced a movie together, "Enigma," starring a young Kate Winslet, in 2001, about the British breaking the Nazi's wartime military code.

Word is that, to mark the anniversary, Jagger, 68, will sing with musical guests Arcade Fire and the Foo Fighters.
