Looking for Yves Montand's version of C'est si bon on YouTube there is only
a one minute performance while I found
this one by
Eartha Kitt (a very interesting singer). YouTube says 1962 but I doubt it as
the song was written in 1947 and poularized by Eartha in a 1954 movie but recorded in 1953 (Wikipedia), the same year as
Yves Montand did (french wikipedia). And of course
Louis Armstrong's version.
