If you have been listening lately you know that there have been rumors swelling about Jimmy Fallon taking over for Jay Leno.  NBC has not come out and said that Fallon is taking over nor have they said he is not. 

Jay still rules the late night ratings beating out all other late nite hosts.  Jimmy will bring a younger audience and if Jay finds himself on the outside, I'm sure another network will scoop him up rather quickly!  Here is the video of Jay and Jimmy singing about late nite.
