Allen, is that the one with the weird drawing of Twardzik on the cover? 1954 IMPROVISATIONS, or something like that? If so, yes. I have the PJ, the Boston 1952 date w/Bird, the Chaloff material, the Mariano date, the sides w/Baker in France... I think I've got it covered, music-wise, but really hope I can read the Chambers before doing the show. I might even go against our listening guide & postpone the program if I don't have the book yet; its appearance was a prime factor in my timing.
