...It's really just a sketch written with the assumption that the person reading it has heard the tune. I didn't write down the melody because it's so simple that it can be remembered by listening to the song a few times.
The 2nd chord in the B section is Ab major7 with no 5th... If you want tensions, the best chord scale in my opinion is Lydian #5 #9.It was transcribed from the NPR Village Vanguard recording from January 7, 2009. Below you'll find a link so you can stream that set and hear the tune. It's the second song in the set and starts around 17:00 minutes in: http://www.wbgo.org/internal/mediaplayer/?podcastID=528
There aren't really any publicly available recordings of this tune besides a version on Youtube with the Polish female jazz singer Grażyna Auguścik.
