Saturday music

I couldn't quite do what I wanted.  There isn't a single track on Booker Ervin's The Freedom Book named for the album title, and there's nothing on youtube to embed the whole album, but if you don't know the album, it's a great one.  Instead, let's go with Duke Ellington & John Coltrane, "My Little Brown Book," from Duke Ellington & John Coltrane.
