Are you MAN enough to defend your love against... 100 GUITARS!?
I didn't have a lot of information about this video when I posted it, but thanks to a PCL visitor who did some great research, now we know...
"de la TV Romande" indicates that it's French-Swiss (i.e., from the French-speaking part of Switzerland). In this case it came from SSR/TSR (Télévision Suisse Romande). It's an excerpt from "Happy End", which won the main prize at the 1964 Rose d'Or Swiss TV festival/awards. (See WIKI LINK).
Apparently the Stones and Petula Clark played live at the awards that year. The whole thing looks pretty demented, in all the right ways."
The song is "Every Night (Without You)" from 1962 by Paul Anka.
