Anybody know who the man/actor is that seems randomly on the finish of La Boum?

This can be a lengthy shot, however does anybody know who precisely the man that seems ultimately of La Boum (1980) is? I don't imagine he's in or acknowledged within the credit. Additionally I don't imagine he seems within the second film. I’d assume he's French and am not very conversant in French actors. Is it extra possible it's only a random particular person off the road they casted? Thanks for any assist.
