Here’s a remarkable short film of the great gypsy jazz guitarist Django Reinhardt, violinist Stéphane Grappelli and their band the Quintette du Hot Club de France performing on a movie set in 1938. It was produced for the British media as a way to create some buzz before their first UK tour. As Michael Dregni writes in Gypsy Jazz: In Search of Django Reinhardt and the Soul of Gypsy Swing:
The Quintette was unknown to the British public, and there was no telling how their new music would resonate. So, Grade sought to educate his audience. He hired a movie crew to film a six-minute-plus promotional short entitled Jazz “Hot” to be shown in British theaters providing a lesson in jazz appreciation to warm up the crowds.
