In addition to the very good Charlotte Gainsbourg news (below), I post this song I recently found. It's Manu by Renaud, sung by Julien Clerc, Charlotte and Francis Cabrel. They did it for the Night of the Proms-ish Les Enfoirés in 2001. Charlotte sounds very much like a young Jane B in this song. Francis Cabrel turns 55 tomorrow (Nov 23), congrats!
