I heard it for the first time in mid 60's.
For me, it sounds like a rock and roll performed by
a great orchestra, with a very beautiful melody.
The violins carry the main theme, backed with exciting drums who gives the "rockanrollesque" sound.
I think this version is much better than the original, performed by his author the french singer Christophe.
In the instrumental pop style I prefer Mauriat, Pourcel or Lefevre's orchestras than Caravelli's, but this version is excellent and I can't find it mistakes.
