Learning Yiddish

[Morissa Rubin <Morissa_Rubin...>]

Has anyone on the Jewish music list had success teaching themselves Yiddish? 
If so, I would greatly appreciate hearing about your experience.  I'm pretty
competent in synagogue Hebrew (can daven, leyn, etc.), but have no knowledge
of German.  Are there effective materials out there (tapes, books) that you
can recommend?
