The Times Daily was more specific about the contents: the show had a Mickey Rooney production number, Elke Sommer in a Dietrich-act, Sammy Davis, Jr. as the Mad Monk Rasputin and in a Chevalier tribute (to which Ray contributed - dancing!), "and you haven't lived until you've seen Ray Charles doing Louise". He also performed Look What They Have Done To My Song, Ma (source).
Archival Television Audio (ID #4089) has shelved the footage.
