Véronique Sanson was one of the guests on the show The Secret Song this Friday on TF1. The singer first saw Zaz arrive on set to masterfully perform In love, accompanied on the piano by the sister of Véronique, Violaine. Secondly it is his son Christopher Stills who added the finishing touches to this magnificent gift. At the end of the performance, everyone embraced each other with great naturalness and complicity.
