The timing of this thread is a mind boggling coincidence, as far as I'm concerned.

I sang yesterday for a Jewish group called the Workmen's Circle. One of their national officers was Joseph (Yossele?) Mlotek, the co-author of "Pearls of Yiddish Song." The gentleman next to me at lunch knew Mr. Mlotek, who passed away about a month ago, and attended his funeral. During lunch he told me about the efforts Mr. Mlotek and his wife made to collect and document Yiddish music.

The title of their last book, "Pearls of Yiddish Song," was the title of a weekly column they wrote as well.

I was so thrilled to be hearing about these two remarkable people and now here's a reference to their collection on Mudcat the very next day.

One small indication of the regard in which Mr. Mlotek was held, is that Theodore Bikel attended his funeral and sang two (Yiddish) songs for him.
