This Video is Garou (oringal Notre Dame de Paris Quasimodo) and Damien Sargue (the original alternate for Phoebus and Gringoire but is most known for playing Romeo in Romeo and Juliette) singing Le Temps des Cathédrales. The song starts at 58 seconds. Garou makes Quasimodo faces and Damien is wearing a Romeo costume.
Enjoy
