Here is a clever little tune by Dexter Gordon and Bud Powell. It is a straight-ahead AABA 32-bar form. The A sections mostly alternate between Fmaj7 concert and Gb7. The bridge is a little more involved, but manageable.
The challenge of this tune is the melody line, which you can find in many fake books. The lines are interesting, sometimes obtuse, and you can hear Ellington's influence.
