Pickin's so slim I should take the week off. A couple of country artists and a few oddities is all I see.
DeGeneres: Jason Aldean and Kelly Clarkson
Conan: Jason Aldean
Conan: G. Love (favors unusual instrumentation)
Letterman: Hank Aaron (rare appearance by the baseball great)
Fallon: Laurie Anderson (never know what to expect from this artist)
Early: Serene Branson (reporter whose odd post-Grammys report went viral)
