A quote from that transcription:

"Jelly Roll Morton was a denizen of the tenderloin, of the sleazy underbelly of life. So we might be shocked at some of the obscene language, the crude depictions of commercial goings on, the brutality and heartlessness depicted. Accept these we must though, if we want to view the world that he worked in, and which in part informed his creativity".

Jelly Roll Morton talks about pianists and other musicians of his time whose names may only be remembered because of his mentioning them-people like Alfred Wilson of New Orleans who won a piano contest at the St. Louis Exposition, and "Tony Jackson" who Jelly Roll Morton admits was the reason he didn't go to that Exposition because he was afraid of competing against. And then there are the musicians "Brocky Johnny, Skinny Head Pete . . . Old Florida Sam and Tricky Sam, and that bunch" who Jelly Roll Morton mentions...And Jelly Roll also mentions:

"Of course, we had King Porter around there — that is, I mean, Porter King — the man that "King Porter Stomp" was named after. He was considered a very good piano player. And of course, we had, er, King — I disremember his name — I think his name's Charlie King, another piano player around there. Baby Grice was another one, that was supposed to be good."

We have surely lost so many stories about talented people. We have lost so many songs and so many tunes from that time and would have lost far more were it not for Alan Lomax [and his family].
I want to take this opportunity to thank them for their work collecting these songs and memories.
