Armando,
too bad you won't be in Belo Horizonte!

Kevin,
I was pulling Donny's leg... but I am kind of disappointed: do you mean that the voices you've heard don't sound like the real thing?!?

Scott,
for this one I have used the chords from the Real Book and you are right: listening to the song, I too find slightly repetitive the progression Cmaj7-C6.
Comment: this is a song that lends itself to be played in a variety of styles: swing, rhumba, bossa...I had even thought to do a version with the Afro-Cuban style: a bit extreme, maybe...
