I tried out this question just now on Google: "Did Bud Powell ever play with Clifford Brown?" This is the AI summary that came back:  I have no idea if Brownie ever played with Bud but this seems like a surprisingly reasonable and useful answer for an AI.  Of course it's hard to be certain it's correct without some research.  A quick look at Brownie's discography did not mention Bud.

I received my shipping notice yesterday (9 January), and delivery is still announced for next Monday (12 January). Keeping my fingers crossed now ... Am really looking forward to that book. Though I am sorry to say that the earlier "Listening To Prestige" session presentation Vol. 1 (1949-53) I ordered and received before Christmas, though really interesting, is a bit of a mixed bag (or "uneven", to put it another way) IMO and to the extent I've so far read it. 

Yes, I love that one too!

You made me hesitate, but I checked the early posts in this thread again and I see that on 24 June last year I posted "10 months till publication might be an unbearably long time, though." Which does indicate April 2026. So it's good to see everything seems to be going to plan with readying the book for publication. (It has happened before that long-awaited books have been been postponed almost endlessly) So I'm definitely looking forward to April.
