Thanks to MorwenEdhelwen1 for providing a link to the article entitled by "Alexander's Ragtime Band at One Hundred" by Benjamin Sears & Bradford Conner.

As a result of reading that article, I published this post on my cultural blog:

http://pancocojams.blogspot.com/2013/08/black-race-markers-in-irving-berlins.html "Black (Race) Markers In Irving Berlin's "Alexander's Ragtime Band".

I also added the following comment to that post:
"As a matter of information, for five years I was a very active member of Mudcat folk music forum. However, for some time I've very rarely posted there for various reasons, most of which have to do with the scarcity of commenters who are People of Color, and my concerns about comments on that forum about race & racism.

Nevertheless, I acknowledge that I have learned a great deal from some Mudcat commenters. And I also acknowledge that I sometimes get ideas about posts on my blog from scanning that forum. One such idea is this post aboout Black markers in Irving Berlin's song "Alexander's Ragtime Band".

Also, for what it's worth, with regard to the subject of that particular Mudcat thread which is about the meaning of "Pickaninny in closet" as it was used in reference to Irving Berlin, I'm largely in agreement with the comments made by Gibb Sahib Date: 18 Aug 13 - 07:11 PM."
