“All the Best” (Live on Letterman)

    Broken Hearts and Dirty Windows: Songs of John Prine is set to be released on June 22, and the man himself joined with “Yim Yames” to perform “All the Best.” The most striking thing about the performance is how weathered Prine seems, sort of like a musical equivalent of Clint Eastwood in Unforgiven. He pairs nicely with the singer from My Morning Jacket, who for some reason has decided to boycott the letter “J.” Though Letterman barely hides his contempt when introducing “Yim Yames,” there is no arguing with the quality of the man’s voice.
