It's the main theme of the show and the very first song ever made for that cause (created by
Coluche).
It was made in 1985 or 86 before Coluche died, the official clip is below. Coluche is the first guy to sing (with a big cap, not a "real" singer
, you can hear Yves Montand singing, right after Coluche (only a small animation of him in the clip though). Jean-Jacques Goldman is the guy singing between two girls. For football fans (soccer in the US), you can recognize Michel Platini at 2:02. You can see lots of scenes of all food stocks amassed to fill those free restaurants for homeless people...
