I'm pre-ordering also. Rest assured, tranemonk. This is essential material. Quite a few of us on this board (Chris A., Lon, Brownie, and others) are somewhat familiar with this material from previous issues, but there is material here that has NEVER been released before. It's just Jelly sitting at a piano and talking and singing (and embroidering - somewhat) his memoirs and accompanying himself on piano the whole time. What I've heard previously (most of the actual tunes (from a previous Rounder issue) and some of the talking (from the times I've heard portions of the original lp release played on FM) is totally fascinating. His complete rap and demo on the development of Tiger Rag from a French Quadrille into a Jazz standard is not to be missed.
Plus - you get a lot for your do-re-mi. Good notes and a copy of "Mr. Jelly Lord" which is the book Alan Lomax put out. It's essentially a transcript of Jelly's rap.
There's another thread on this but I still don't know how to use the search enginge.
edit to add: and I don't know how to spell search engine either !
