The other guests were Jerry Lee Lewis, Lulu and Marilyn Michaels. At 10:24:40 there's a brief snatch of Georgia, followed by Engelbert's introduction of Ray Charles, who then plays:

• Georgia On My Mind [partial; my conjecture, BS] 
• Let The Good Times Roll
• The Sun Died
• Makin' Whoopee (with Engelbert Humperdinck)

Probably after that, they did the duet on Release Me. Also read this.
