I wonder if anyone can answer this…  Laura Brannigan had a smash hit with the song "Gloria" in the early '80s.  There was another version that came out quickly after Brannigan's that was sung in French, but had an almost identical arrangement and sound as Brannigan's.  I think the singer's name was Sylvie, but I am having a devil of a time finding out.  I would like a copy of the French version if I could find it.  I tried to buy the vinyl record at the time I heard it, but the guy said that he bought it on a trip to France, and wouldn't sell.  Anyone have an idea about this?  Here may be a clue:  I saw a video on YouTube of Sylvie Vartan singing "Gloria" on stage (in English.)  Sylvie Vartan isn't French, but has mostly recorded in French.  Could it be her?  If so, I can't find a record of her singing "Gloria" (except for in English on YouTube.)  Anyone???

Here I am!
Gloria came out in 1979 by Umberto Tozzi, an italian singer. Gloria is an italian song in italian language. Then, in early '80s, laura Branigan purchased copyright from Umberto Tozzi and realesed the "english version" you know.

Thanks for that info--I was not aware of the song's origins.  However, there still was a French version that appeared very quickly after Brannigan's.  In fact, if you didn't listen carefully, you might not notice that it wasn't Brannigan--the arrangement was that similar.  But, I was a French minor in college, and it jumped out at me.  I am still searching for the French version of "Gloria"...
Thanks for the information.
