Advance notice for tv appearances

[Rowbes]

Does anyone know of a good reliable resource to find out about tv appearances before they happen? GMA and SNL just snuck up on me this month, and I'd like to stay in the loop. Especially for late night tv gigs, its fun to see what the Muppets do when they're allowed to get a little extra raunchy.
I was delightfully shocked to see how far Whitmire took it on the Daily Show a few years ago, when Kermit divulged some very personal info about his love life with Piggy. Did anyone else catch that one?

actually GMA was listed on the official site forawhile. SNL was a surprise though.
