A dance show, enthusiastic and exciting, 1h30 for all audiences. Arriving on her "Vélo-Guinguette Mobile", Elsa Swing, review leader, tells us the crazy story of French balls from 1900 to the 50s. Through 4 acts, Elsa Swing and her partner Lee Roy, invites all participants to 4 dance initiations: the waltz, then the charleston, the swing and finally the rock'n roll! A journey through time to transmit and keep this choreographic heritage alive.
