Thanks guys!
I tried to search a little bit bio of Nana, and got this "in 1969, she released her first full-length British LP, Over and Over, a smash hit that spent almost two years on the charts". So, did Nana really sing the French version before the English version? Wow, I wish I could hear that French version... BTW, are most of Nana's songs in French? Yeah right, a fan of Nana would help me out
