Steve Earle ‘The Ballad of Kenneth Parcell’

With tongue firmly planted in cheek, Steve Earle sang "The Ballad of Kenneth Parcell" over the closing credits of the latest episode of 30 Rock. "It's a really funny show written by really smart people," the singer tells Rolling Stone. "There's something especially therapeutic about comedy if you don't do it every day, a welcome break from everything you do being taken so seriously, especially by yourself." Earle's most recent album, I'll Never Get Out of This World Alive, is nominated for a Grammy in the Best Folk Album category.
