Going thru some boxes of old stuff today and found a letter from John Litweiler postmarked December 4, 1972 (I was living in Madison at the time). The note ends with "Koester will record H. Threadgill, w. Fred Hopkins, McCall & Claudine Myers, piano. sometime this month".
The date never happened, but it still sounds dandy to me. "Amina Air" seems like a nice title.
