I don't remember if I've seen this mentioned anywhere, but you can listen to an interview in french (and english) here by Charles Delaunay that isn't included on any CD's. Benny tries to speak some french, then Charles Delaunay mentions Django is going to appear as a guest on one of Benny's concerts or something, to which Benny exclaims that it was supposed to be a secret. I'm guessing Django then says he and Benny met at the 400 club (New York City) and after that Eartha Kitt speaks in french. (singer, Catwoman, actress....)
Django's "Oui" sounds more like "Wei", a translation would be nice!
Comments
Q: Django, lorsque vous étiez aux États-Unis, lorsque vous étiez à New York, vous avez certainement entendu Benny Goodman. C'est à ce moment-là que vous avez fait sa connaissance?
A: Oui, je l'ai entendu à 400 Club à New York.
Q: Et il vous a demandé de jouer, je crois, au concert l'après-demain?
A: Ouais. [cross-talk]
Translation:
Q: Django, when you were in the US, when you were in New York, you certainly heard Benny Goodman. Was it at that time that you met him?
A: Yes, I heard him at 400 Club in New York.
Q: And he asked you to play, I believe, in concert two days later?
A: Yeah. [cross-talk]
Django and Benny performed together for the first time at that concert, according to Django they were just going to improvise some tunes, rehearsal was done on June 1 1950.
They met at the 400 club in NYC in 1946, but Django wasn't allowed to perform with anyone except Duke Ellington and Band due to US laws concerning visiting forein musicians.
There's another interview from June 8 1950 just before the concert here:

This 1988 book, "meticulously researched with Goodman's active participation" suggests that this concert was radio broadcast and at least part of it actually recorded to disc. To read more one has to buy the book I think.
Page 200 (June 8 1950):
"At least in part, the Paris concert, at the Palais du Chaillot, was broadcast by a French radio network. Extant recordings were taken off the air onto acetates. Because of disc limitation, intro's of some of the selections are clipped, and some have their middle portions excised. But overall, their quality is good, and they are a worthwhile souvenir of Benny's farewell to Europe in 1950."
If Django appeared as a "surprise" guest, it's possible they did it as an encore and thus it wasn't recorded, but who knows?
