The "History" section for the page on the Westgate Las Vegas hotel (formerly the International, then the Hilton) contains this passage:
"On July 31, 1969...Elvis Presley performed the first show of what would become a seven-year run at the hotel... Many of the performers who worked the International before Presley were upset at their disrupted prospects. Comedian Chuck LaFille, who left a regular host job on
Beat the Clock to host at the hotel, was so irate at the plan he reportedly destroyed Presley's under-construction dressing room and threatened violence at hotel executives."
LaFille was apparently a sub-host for Bud Collyer in 1956; I can find no evidence that he was involved with the '69 revival in any way. I suppose it's possible that he had a 13-year residency at the hotel, but can find no record of this either.
(On a related note, LaFille is apparently still alive and well.
His XTwitter account is...interesting.)
