Festival de Eurovisión (1956 - 1966)

Despite track #9 being around 10 seconds shorter than most other tracks linking to the same recording, I believe that it's just pitch-shifting done to the best-known 1964 recording of "Non ho l'età", rather than a completely different take.

Track #11 includes a version of "Merci chérie" that I didn't know of, as it sounds nothing like the 1966 original or the 1972 re-recording which also shows up often on compilations. A scan of the audio on Picard for fingerprints gave me the following AcoustID entry which sadly doesn't help much to identify it either, as the page doesn't contain much user-submitted info:
