1-Thanks all!
2-Sorry I didn't answer before but today is Tuesday and Tuesday is the day I visit my mom so no Mudcat till I go back home.
3 -The lady sent me a home-made recording. It sounds like a lullaby. She says she only has the recording and the "lyrics". I've just emailed Lisa for her to post the request on her blog, I'll tell you as soon as she's posted it along with the recording.
4- Felipa, if your question about working out the Yiddish spelling from the transliteration was directed at me, the answer is no, neither the other way round.
BUT... I've just come across a tool that does it: Lexilogos Yiddish Keybord. When you get the Hebrew characters, you copy and paste them into this tool that encodes the text for you in all those &#... entities that display properly on Mudcat. Too bad we can't download the tool on our computer!
The trouble is that the transliteration > Hebrew works whether the spelling is correct or not, so when you put the "Hebrew" into a translator "Yiddish" > "whatever language" you get gibberish.
