Well, on this evening's show (that's Tuesday, January 12, depending on when you are reading this...), two of the guests are Robin Williams and Jonathan Winters. I suspect it will be quite entertaining. (You can read here about how to find it on your system.)
And while I'm at it, I'll add another Media Alert, though I'm not 100% sure when it's on.
James Corden has a fun feature on his show every once in a while, Car Karaoke. He drives around with some famous singer in the car with him, and they sing the person's hits to the radio. On Wednesday's show, he'll be doing that with Adele. They've shown promos, and it looks very entertaining.
Here's the problem, I don't know when "Wednesday's show" is. The program comes on CBS at 12:35 AM. So, is Wednesday's show tonight (Tuesday), but it officially airs on Wednesday? Or is Wednesday's show the one that is Wednesday night, but it officially airs on Thursday???
The safe way to deal with this is to DVR both nights. (And then we'll know what they consider a night's show for the future...)
