I've actually seen an album or two where Ray Charles plays alto sax--I believe for the entire album. I can't track down the info though right now.
Edit to add that it was a tribute to Charlie Parker, iirc
That's "Soul brothers", with Milt Jackson. Ray plays piano on most, if not all, tracks, but gets in some alto playing, too. And Milt gets in some piano playing, when Ray's on alto, and guitar playing. But they're both on their main instrument most of the time.
But you've reminded me about
Ray Charles - Genius + Soul = Jazz - Impulse
Ray Charles - Genius + Soul = Jazz Live - Golden Age of Jazz
Ray plays organ throughout these two albums.

That's the one, yep. Oh, I didn't realize it wasn't the whole album. How are the Ray Charles organ albums?
