Allow me since im in Houston watching:
they did change a few spots on his Jay Leno show set, but that's just about it, they now have a new opening, but wasn't eye catching to me, there is a segment on Jay finding a new desk, going to people's houses looking for one, and Jamie Foxx is on there tonight, very happy that Jay is back... by umm... performing a small 5 second concert welcoming Jay back, and popping champaign on the set before giving it to an audience member. And i think Jay's jokes at the beginning were the same as they were at 10/9c.
To summarize, the show wasn't eye catching, but entertaining enough to still watch.
