He's jazz musician Slim Gaillard, and the song is usually known as something like "Yep-Roc Heresay." And now the explanation:
So enjoy. It's more diverting than arguing about settlement building. Good music, and it makes you hungry for Lebanese food.
That’s right, he’s singing about food: yabra (i.e. stuffed graped leaves), harisseh (a semolina dessert), kibbeh bi-siniyyeh (a dish of meat and bulgur), lahm mishweh (grilled meat), etc.
A great tune. So what’s the back-story? I’ve been able to dig up various bits and pieces, but perhaps one of the readers can help out. The Wikipedia page on Gaillard suggests that he was reading from an Arabic menu, while this page claims that it was an Armenian menu, and that the song was actually “banned on at least two Los Angeles radio stations for its suspicious lyric references to drugs and crime…” (!)
The song has since become something of a standard, as evidenced by this rendition by what looks like some kind of wedding band. (I don’t think I’ve ever seen anything so hysterical. Who knew that Levantine cooking lent itself so well to vocalese?)
