This program aired two weeks after "Lucy Calls The President", the last time that Lucille Ball worked with Vivian Vance, Mary Jane Croft, and Mary Wickes. Earlier in 1977, Lucy lost her mother, Dede, who was in the studio audience for most all of her appearances.
Lucille Ball tells the story of how she was supposed to play the role of the elephant girl in Cecil B. DeMille's epic circus film "The Greatest Show on Earth" (1952) but became pregnant with a little girl. Now all grown up, Lucie Arnaz is on "Circus of the Stars" as the elephant girl. As a finale, Lucie lays on the ground and allows the elephant's foot (with painted nails) to hover inches from her face. This is the same stunt that the elephant girl (played by Gloria Grahame) did in "The Greatest Show on Earth." Before doing it, Lucie calls out "It's alright, Mom!"
After Lucie Arnaz finishes her act, the show cuts to the audience giving a standing ovation. The next shot is of Lucille Ball standing in the ring, so the ovation was for Lucy, not Lucie. Ball brings out her daughter who says "I made it!" and pats her mother's tummy in acknowledgment that it was because of her that Ball turned down the role in 1952 film "The Greatest Show on Earth". Ball did get to do "The Greatest Show On Earth" when it became a Desilu TV series in 1963. She played an equestrian dealing with an orphaned circus boy in what turned out to be her first dramatic role for television. Except for the final circus parade, this is the only time that a Ringmaster (Lucy) is on the set with one of the acts.
