I dunno, Wolfgang. The only Yiddish I can even attempt to read is phonetically transliterated. It's supposed to be written in Hebrew letters. The pronunciation is similar to German, but certainly not exactly the same. I've been trying to learn Kiddish pronunciation by listening to Klezmer CD's (The female lead singer in the Klezmer Conservatory Band has a marvelous voice, by the way). Unfortunately, I don't have a recording of this song, and I still haven't found a really reliable text. I'm still looking. Maybe I'll have to buy the book.
