Blue Rondo a la Turk, sung by Dave Brubeck. This guy is freaking awesome; I couldn't sing like that man if I tried. I especially love how he sings so perfectly in 9/8 time. I play this song in my jazz band, and a lot of the performers have trouble transitioning from 9/8 to 4/4 and back. Pretty good song, I'd say, if a bit tricky to capture the rhythm of.
