Yup, Bob Dylan and Leonard Cohen are Jewish too, and so are a host of other great songwriters, like Paul Simon and Carly Simon (I presume). A major contribution indeed. Cohen seems to consider himself a Jew who practices Buddhism, while Dylan, of course, has had major forays into Christianity as everybody well knows. Cohen pointed out in one song that he doesn't pretend to understand the sermon on the mount at all. Interesting. I find it quite comprehensible. Maybe he was just trying to come up with a neat-sounding line in that particular song, rather than stating a firm belief of his own.
