I recently came across this great performance that The Black Keys put on while on Letterman this past Tuesday.  Doubling the size of the band for this performance gives this song a bit more activity and texture, and while the addition of the bass and keyboard dilutes the funky bluesy feel a tad (my opinion), the end result is still great.  Also, bonus points for the standard super-weird comments from Letterman at the end.  “Beautiful drums, are these yours?” – who says that?
