The Charlie Parker Story is an LP record by Charlie Parker, released posthumously by Savoy Records. While many of the tracks on this album had been previously released on other formats, this is the first album that chronicles the entire session, recorded November 26, 1945, including all takes of all pieces. This session is famous in that it is the first recorded under Parker's name. It is also controversial, in that to this day it is unclear who the pianist and trumpet player are on all of the tracks.

"Ko-Ko" is a 1945 bebop recording composed by Charlie Parker. The original recorded version lists Parker on alto saxophone with trumpeter Miles Davis, double bassist Curley Russell and drummer Max Roach. Due to the absence of Bud Powell, Dizzy Gillespie was enlisted to play piano, instead of his usual trumpet. Pianist Sadik Hakim, then known as Argonne Thornton, was also known to be present at the session. Rumors persist to this day about precisely who played trumpet and piano on this piece; some claim it's young Miles Davis who plays trumpet and Gillespie comping at piano, on both takes; most claim Gillespie plays trumpet and, or instead of, piano; some claim Hakim is the pianist on all or part of one or both of the takes. However, Miles Davis confirms in his autobiography that he did not play trumpet on "Ko Ko":"I remember Bird wanting me to play "Ko-Ko," a tune that was based on the changes of "Cherokee." Now Bird knew I was having trouble playing "Cherokee" back then. So when he said that that was the tune he wanted me to play, I just said no, I wasn't going to do it. That's why Dizzy's playing trumpet on "Ko-Ko," "Warmin' up a Riff," and "Meandering" on Charlie Parker’s Reboppers, because I wasn't going to get out there and embarrass myself. I didn't really think I was ready to play tunes at the tempo of "Cherokee" and I didn't make no bones about it."
