This was Lucille Ball's third of four appearances on "The Carol Burnett Show." A week after this episode first aired, the script for Carol's second appearance on "Here's Lucy" was finalized, although it would not air until March 2, 1970.
Like Lucille Ball's sitcoms, "The Carol Burnett Show" also aired on Monday nights. Earlier that evening, "Here's Lucy" aired "Lucy, the Cement Worker" (S2;E10) guest-starring Paul Winchell.
In Carol's opening remarks she talks about a recent Halloween at her home. She also tells the audience she was born in San Antonio, but raised in Hollywood since the age of seven. Lucy's husband, Gary Morton, is in the audience, but is not introduced.
As the a vaudeville act, Lucy and Carol sing "Happiness Cocktail" while strumming ukuleles. Lucy then breaks out a saxophone, and Carol a coronet. Although Lucille Ball had a basic knowledge of both saxophone and ukulele (and demonstrated it on her sitcoms), she is pantomiming to the offstage orchestra, as is Carol.
