As I suspected, Wolf, your accent has authentic roots. My training is in German, which I've spoken most of my life; and I picked up Yiddish by listening to a lot of recordings - many from singers who came from Poland and Lithuania. I think my Yiddish accent is pretty good, but probably heavily influenced by German.
But authenticity aside, I have my Judy Bressler fantasies. I love her voice, despite her New York/New England Yiddish accent.
