While I was poking through the Copyright Office cardfiles I came across these two excellent Yiddish Theater songs, neither of which I can find anywhere. If you locate either of them for me there is a reward!
Men shikt nit keyn katz nokh keyn smetene (by Yosef Tanzman)
aka "One doesn't send the cat to get the sour cream"
Mr. Malach Hamooves ich bin busy (Nellie Casman)
"Mr. Angel of Death, I'm busy."
The Angel of Death is usually spelled in Yiddish "malach ha moves" or "Malach ha-Mavet"
