That's a good question, Sol. All I found was this (click):
Indeed, the Six-Day War song "Nasser Mechakeh L'Rabin" has its origins -- the music, if not the lyrics! -- in a bawdy Yiddish tune.
By way of introduction, a version of "Nasser Mechakeh L'Rabin" (sung by the Doodaim) appears on the Hed-Arzi compilation album "Jerusalem of Gold: Songs of the Six Days [sic] War." According to the liner notes, a "folk tune was used by Haim Heffer for his song 'Nasser Waits for Rabin,' which helped keep spirit high during the battles."
But an earlier tune -- with the same music and even the ai-ai-ais ending each line -- can be found in an innocuous-looking French 78, released on the Saturne label (just after World War II, from the looks of it) and with two sides of Yiddish "folklore arranged and interpreted" by "S. Berland et son orchesare" (orchestre is French for orchestra; I'm not sure what orchesare refers to specifically). Both sides feature an unidentified male vocalist and chorus; possibly the lead singer is S. Berland himself.
The A-side is a slow version of "Yidl Mitn Fidl" (as it's spelled on the disc). The B-side, and the inspiration for the Six-Day War song: "Der Rebe Mit Di Schikse." Three guesses as to what it's about!
