I purchased that and can attest that it's a very good transcription and worth the money as it also has transcriptions of the solos too.
If you're looking for the J&K+6 stuff though, which gets lumped together because the CD release of that included the LP of The Great K&J as well as the K&J Octet recordings, it is unfortunately NOT included. Interestingly, both albums have a totally stacked set of players:
Artwork – Arnold Roth
Bass – Milt Hinton (tracks: A2, A3, A5, A6, B2, B3, B5), Ray Brown (tracks: A1, A4, B1, B4, B6)
Bass Trombone – Bart Varsalone*, Tom Mitchell*
Congas, Bongos – Candido Camero* (tracks: A1, A4)
Drums – Osie Johnson
Piano – Hank Jones
Producer – George Avakian
Trombone – Eddie Bert, J.J. Johnson, Jimmy Cleveland, Kai Winding, Bob Alexander*, Urbie Green
For what it's worth though, the Octet stuff is actually pretty easy to transcribe. Although I've admittedly only transcribed the Night in Tunisia from the soundtrack, the way that Kai's part is mixed, he sticks out like a sore thumb in stereo at 50% speed, so it's really easy to figure out the note of the top voice.
Also side note, I know JJ was basically a genius at writing but now that I've transcribed it, WOW there are some things that sound really, really impressive that are actually very simple to play. Just an all around magnificent arrangement done by him.
