From Wikipedia:
The Hollywood Palace is an hour-long American television variety show that was broadcast weekly (generally on Saturday nights) on ABC from January 4, 1964 to February 7, 1970. It began as a mid-season replacement for the short-lived Jerry Lewis Show, another variety show which had lasted only three months. It was staged in Hollywood at the former Hollywood Playhouse (where Jerry Lewis' series had originated, temporarily renamed "The Jerry Lewis Theater" from September through December 1963) on Vine Street, which was renamed The Hollywood Palace during the show's duration and is today known as Avalon Hollywood. A little-known starlet named Raquel Welch was cast during the first season as the "Billboard Girl," who put the names of the acts on a placard (similar to that of a vaudeville house).
Unlike similar programs such as The Ed Sullivan Show, guest hosts were used instead of a permanent one. Among the performers and hosts on the show were Bing Crosby (who made the most appearances as guest host: 31 in all, including several of the annual Christmas shows), Dean Martin, Bette Davis, Frank Sinatra, Milton Berle, Sammy Davis Jr., Sid Caesar, The Rolling Stones, Groucho Marx, Joan Crawford, Tony Bennett, Judy Garland, Jimmy Durante, The Supremes, Ginger Rogers, The Temptations, Phyllis Diller, Elizabeth Montgomery, and many other famous faces. The off-screen announcer for each program was Dick Tufeld.
A number of popular music performers got their start on the show. For example, The Rolling Stones made their first US television appearance June 3, 1964, and The Jackson 5 made their first national television appearance on the October 14, 1969 episode. The folk-rock group We Five performed their hit "You Were on My Mind" within a few weeks of its release in 1965.
In a famous June 1964 telecast, The Rolling Stones were repeatedly ridiculed by host Dean Martin when they did two songs "I Just Want To Make Love To You" and "Not Fade Away." Later, when the Stones proved popular, reruns of their performance were shown with the current host and the original Martin comments edited out.
