After six seasons of The Lucy Show, Emmy winner Lucille Ball would only consent to continue with one provision----that her children would co-star with her.
Daughter Lucie Arnaz had made a guest appearance on The Lucy Show, and her brother, Desi, Jr., had appeared with his father on The Mothers-In-Law. Now, they'd be together with their mother in Here's Lucy, which anchored CBS' Monday lineup, alongside, of course, Gunsmoke, for six seasons of its own (1968-74).
As was the case at the end of The Lucy Show's run, Lucy relied on major celebrity guest stars, such as Elizabeth Taylor and then-husband Richard Burton, and Joan Rivers, to help reel in the viewers. Well, it worked, and one must assume that the series ended because Lucy had finally decided to walk away after 12 seasons. She'd spend the rest of the decade carefully selecting movie roles and was feted by Dean Martin on his Celebrity Roast.
