Did Brigitte Bardot plagiarize The Chordettes' "Mr. Sandman"?

Apparently, I'm the first person on the Internet to notice that Brigitte Bardot's 1968 song "La Madrague" (at time-code 0:25) has an electric piano part that sounds exactly like the memorable one from The Chordettes' "Mr. Sandman", time-code 0:30.

Bardot's version is just missing a couple of extra notes at the end of the phrase that would otherwise have raised concerns of copyright infringement.  Now what could possibly be more important than debating this for the next 5 years?
