During the years of world war 2, Grappelli and Reinhardt split up and played with different groups. During this time Grappelli played a lot of jazz piano. After world war 2 Stephane Grappelli and Django Reinhardt and the Quintet of the Hot Club of France got back together briefly during the late 1940s and then disbanded.
