I was wrong about "Another Night in Tunisia" -- the solo Jon sings starting around 1:40 actually has lyrics. I think the melody scatting for most of the rest of the song is actually Bobby McFerrin.
Oh, there we go, the scat solo starting at 2:30 in "Ray's Rockhouse" is Jon.
Weirdly enough, if I cam to believe Discogs got the liner notes faithfully, they're not crediting Jon with singing a solo on "Airegin". I'm still 99% certain Jon sings the last solo in that song. (Interestingly, singing lyrics over his own scat solo from the original Lambert, Hendricks & Ross recording of "Airegin".) For sure it sounds like him, no one other than Manhattan Transfer is credited with vocals on that track, and when they recorded it live they don't even attempt to sing it, replacing it with a sax solo.

He does get a credit for vocals and lyrics in Discogs, but they don't say which track:
