In December of last year, while searching the internet, I came upon a compact disc of French music from the Thirties. I ordered a copy from Europe, and it arrived today. The disc contains "Je n'ai qu'un amour, c'est toi" by Hélène Caron, and it is a match for the version found in Prix de Beauté. Additionally, the linear notes state the song is from the film (as well as indicates that this recording was released on the Parlaphone label). "Je n'ai qu'un amour, c'est toi" is a truely charming song. And, as this is one of three versions I have found recordings of, a perhaps popular song in France in 1930. I plan on adding this newly discovered recording to RadioLulu sometime soon.
I did a Google search on Hélène Caron, but turned up nothing. Does anyone know anything about her? Did she ever record anything else?
