|L: with Dinah. R; with Eddy Arnold, Johnny Mercer|
The TV page of the Oswego Palladium from 22 November 1967 decribed the program as "an hourlong tribute to the new recording center of the world. [...] The Stony Mountain Cloggers do their bit; the Everly Brothers perform; Johnny Mercer joins Dinah for Moon River, and solos to his country song Gentle On My Mind; Ray Charles sings Yesterday, duets to Cryin[g] Time with Dinah; and the whole cast performs a country hit parade medley at the close."
Here's the audio (and some video of the) complete sequence:
The BBC documentary Johnny Mercer: The Dream's On Me (2009), used footage from this same Kraft Music Hall show. Ray is seen sitting at his piano, doing a cross talk with Dinah, playing the first notes of Georgia, when Johnny Mercer walks in, claiming (sort of) his role in a duet on that song (starts at 4:10):
A reviewer on Amazon came with a piece of information that I found hard to believe: "There is a non-Mercer song clip in the show, him singing Carmichael's Georgia On My Mind with Ray Charles."
There was a historical connection between the two singers and this song, though - read this.
