Speaking of Joyspring -- Manhattan Transfer does a version of this, where they fit words to the actual solo.
While we're on the subject: Clifford Brown's son is a DJ on KCSM (San Mateo). He didn't know his dad very well, obviously.

Jon Hendricks fitted the words to the actual solo. Sorry, giving the credit to MT didn't feel right. Article about it:
Clifford Brown’s “Joy Spring”: Jon Hendricks’ Vocalese Genius https://www.tuneintoleadership.com/blog/jon-hendricks-vocale...
Jon Hendricks was awesome! Hear his scatting (and lyrics) on Airegin: https://www.youtube.com/watch?v=Ul54NWmwLxs
He also wrote the lyrics for their versions of "Birdland" and "Four Brothers", and maybe four of the tracks on Swing, and probably a bunch of other stuff I'm not thinking of.
Oh, there we go, the scat solo starting at 2:30 in "Ray's Rockhouse" is Jon.
He does get a credit for vocals and lyrics in Discogs, but they don't say which track:
