The original score was adapted by Miles Davis in 1950, who created an arrangement that kept Shearing's chord changes and main theme, but replaced the composition's bridge and ending with new melodic material.
Davis also did a complete rewrite of "Conception" in 1950 (creating an entire new main theme) for his Birth of the Cool nonet, giving the composition the title "Deception".
Recorded in March 1950, "Deception" retained the rewritten bridge melody from Davis's 1950 "Conception" arrangement, as well as Shearing's original chord progression.
Porter notes that Shearing's later commercial success and turn from bebop to "middle of the road" instrumental music could have influenced the memories and opinions of the musicians that Pullman cites for evidence.
While Miles Davis immediately adopted "Conception" into his repertoire upon its initial publication, no record exists of Powell playing the composition, or any of its motifs, until 1953.
