Additionally: All this week is Pink Floyd Week apparantly to publicize the re-release of DSOM.
For the longest time I didn't want to like Fallon, but on the whole, he has (IMHO) eclipsed all the other Late Night Talk Shows by a considerable measure.
He has great Talent himself, he has great guests, a very HIP band, a good sideman, and the format is totally adequate.
Only downside is the time slot. (as I need my sleep)
