By now, you've seen this clip from American Idol.
Here's Jimmy Fallon's cover of "Pants on the Ground" as performed by "Neil Young."
From the outset, I really wanted to like Jimmy Fallon's version of "Late Night" but I've come to a couple of unshakable conclusions.
A. He may very well be one of the nicest people in Hollywood or anyplace else.
B. That trait doesn't translate very well into a late night talk show host.
The best hosts historically in the format have a dark side to their personality. Fallon's "Mr. Nice Guy" approach would be much better suited for the 8th hour of the "Today Show" or whatever that thing is that Kathie Lee is a part of.
