I worked on Montmartre. It seems to have been composed by Rex Stewart in 1939 and it was recorded by him with Django Reinhardt. It also became known as Django's Jump.
I like it as it has an easy, pleasant melody, an A - A - B - A 32-bar structure that is simple to improvise upon.
Here's the leadsheet for Montmartre that I came up with. I think it not far from correct, but I'm uncertain whether my two G7 bars would not be better as C minors (resulting in 4 C minors in a row). The effect would be different but would still sound fine.
