Looks like the episode might have aired on May 18, 1971...if "Jack Zinion" might be Jack Binion??

"From Caesar's Palace in Las Vegas. Merv's guests are actress Zsa Zsa Gabor, singer Vic Damone, actor Doug McClure, Anita Laurie, Jack Zinion and Little Anthony and the Imperials."

disclaimer: I didn't upload, download, or try to watch it...
