This month's song is as classic as it gets in this genre. Written in 1939 (hence the name) by Django & Stephane, it was first recorded by the Hot Club on March 21, 1939 in Paris. That version remains my favorite. Other Django recordings of it are from Paris in 1947 & from Rome in 1949.
This is a standard that every gypsy jazz guitarist should know. It is often called at jams, but the form is quite long, so sometimes forms will be shared by soloists so that it doesn't go on forever. (My trio will sometimes skip the bass solo to trim down the time).
Some charts have the A sections beginning with the 1 chord (Bflat) while others have them starting with the 6 chord (the relative minor, Gmin). I've always thought it was nice the way they have it go to G major at the end of each A section. Here's a link to the aforementioned version:
Interestingly, legend would have it that in 1939, the Quintette had become extremely popular and every American jazz artist that visited Europe sought after Django. Indeed, Duke Ellington met him a few weeks after Django recorded this. Other notable recorded versions include those by Pearl Django, David Grisman and Charlie Byrd. I'll post the chart that my band uses later (we use the one with the A sections beginning with Gmin).
