Three days later the concert was repeated, and in total 80 further concerts were organised before the liberation.
With the outbreak of war, jazz floundered. Many key musicians were called up to fight or left for the safer shores of the US (such as Ray Ventura and Jean Sablon). Grappelli and Reinhardt were in Britain; Grappelli decided to wait out the war, but Reinhardt returned to Paris before being forced to flee with the invasion of France. On 16 December 1940, however, Delaunay organised a jazz festival to revive the genre in France. The event sold out in 24 hours. Three days later the concert was repeated, and in total 80 further concerts were organised before the liberation.
