From 1961, here's a label sampler (Columbia) that has a nice little collection of tunes. It never hurts to start off with the Man in Black! (Following him up with Percy Faith, Roger Williams, and Mitch Miller kind of kills the momentum, though). Still, an all-harmonica arrangement of a big band tune can't fail to entertain, there are two jazz tracks that move along well, two soul tunes, and a folk-revival cut.
