And another one I heard tonight (by the wonderful Andres Mustonen and Hortus Musicus): Walther van der Vogelweide's "Palestine Song", a.k.a. "Nu alrest lebe ich mir werde". We got two verses. It's such a beautiful tune you'd think you'd get a lot more, but nobody ever sings the whole thing, for good reason. It was written around 1204 as a recruiting song for the Fourth Crusade. There are about 30 verses in all, starting in a tone of mystical exaltation at the prospect of being a pilgrim setting foot in the Holy Land for the first time (this being the bit people sing these days) and ending with "sock it to them fuckin towelheads" in Old High German. With, I think, "let's sort out the Christ-killers" in between. It seems to have been one of the most politically effective songs in history.
