If anyone on Louis C.K.’s mailing list wasn’t thinking of watching tonight’s Saturday Night Live already, Louis himself has a final word for them.

The New York comedic hero has built one of the most lauded T.V. shows, Louie, as on his own as any T.V. show can be while still managing a new hour of stand-up material seemingly every week. That said, he’s not a man with a million voices and characters or seemingly the capacity to do that, making his appearance on the sketch show an interesting one.

The episode, which in Louie’s e-mail to his fans he says is “completely most probably happening”, should also be an emotional one thanks to Sandy. Not only is he appearing on SNL, a show that very much wears its ties to New York City proudly, but Louie himself is a long time resident.

In the message, he writes about walking to 30 Rock this past week for rehearsals:

And for me, the village being the very place that made me into a comedian and a man, to walk through the heart of it and feel like, in a way, it was dead. I can’t tell you how that felt. And you also had a palpable sense that inside each dark window was a family or a student or an artist or an old woman living alone, just being int he dark and waiting for the day to come back. Like we were all having one big sleep over, but not so much fun as that.

I’m guessing tonight will be something special.

(F.Y.I., as long as we’re talking about mailing lists, the most entertaining music-related one I’m on his for British Sea Power. They might not be the most informative since parts of them seem to go through some free-association generator before they hit my inbox, but they’re a hundred times funner than the million “we’re playing L.A. this weekend” e-mails going around out there.)
