The two melodies [in Bruch's Kol Nidrei, IO] are first-class. The first is an age-old Hebrew song of atonement, the second (D major) is the middle section of a moving and truly magnificent song "O weep for those that wept on Babel's stream" (Byron), equally very old. I got to know both melodies in Berlin, where I had much to do with the children of Israel in the Choral Society. The success of "Kol Nidrei" is assured, because all the Jews in the world are for it eo ipso."
