Regarding the CD reissue: All tracks were mixed to and mastered from digital tape using the Mitsubishi X-80 tapereorder in January 1989. Besides Various - The Greatest Jazz Concert In The World with SID / Mould Codes, there exists a variant without any SID or Mould Code, possibly an earlier release, materialized soon after its mastering in 1989 (cf. Various - The Greatest Jazz Concert In The World).
According to the booklet the tracks were recorded in New York, Hollywood and Oakland in June and July 1967. According to the itinery and recording information compiled by W.E. Timner in "Ellingtonia. The Recorded Music of Duke Ellington and His Sidemen", Scarecrow Press, Fifth Edition 2007 at least all tracks with participation of Duke Ellington, His Orchestra or indivdual members of his organization must have been recorded on the two Jazz At The Philharmonic concert dates: 1967-03-26, NYC, live at Carnegie Hall, 1st concert (track 2-8), 2nd concert (tracks 1-11, 2-1 to 2-4, 2-7, 2-9, 2-10, 3-6 to 3-15) 1967-07-01, Los Angeles, CA, live at the Hollywood Bowl (tracks 1-4 to 1-8, 1-12, 1-13, 2-5, 2-6, 2-11 to 3-5
All tracks without Ellingtonians were most likely recorded at the same dates or at least around the July 1st date, namely on June 28 and 29, 1967 - as Norman Granz wrote in his liner notes for their first release in 1975.
Track 2-7 is misspelled in the booklet and on the tray card as Mount Harrissa.
Navid got this for me on my birthday. I really appreciated because I was very lonely around that time. Despite him not knowing what jazz I liked, he still went out and tried to get me something. I appreciate that just as much as if someone had gotten me a Houston Person record or a Roy Hargrove live recording. Thanks, Navid.
