On stage, several generations live together. To make the machine work, the Gaillards will be doing their utmost to get the audience singing along, reeling off song lyrics in a thousand different ways, with all their energy and using bric-a-brac systems, each more eccentric, ingenious and surprising than the last. From Brel to Stromae, come and breathe new life into the songs of yesterday and today, to tell stories, reminisce and feel good.
