Yes, it was seeing and hearing a Palestinian kid singing that great number by the Bendaly Family, "Do You Love Me?" that captured Ehrenreich for Palestine.
Back in 2007 I did a post about the song called "Is this the best clip of Arab music ever?" Tongue in cheek of course, because the song is sung almost entirely in English, but also heartfelt, because it is great Arab music. And since then, a couple more posts, one with a bit more info about the Bendalys, and links to videos I particularly like, and another about a re-fix of the song by Dub Snakker.
Great to know that the Bendalys continue to be loved. And finally, go read Ehrenreich's book.
