Ethel Merman as Agnes Schmidlapp, who is staying with Lucy and Viv, has agreed to sing at the Cub Scout charity revue. While Lucy and Viv sew the costumes for the show, Lucy becomes a bit resentful and teary eyed that she was not included and can not perform at the show.
Sentimental Merman feels badly for Lucy and comes up with a new finale that stars herself, Vivian, Mr. Mooney, and Lucy in a salute to show business from vaudeville through today.
The finale, "There's No Business Like Show Business," features Lucy and Mooney in a silent film take-off, Vivian as Shirley Temple singing "On the Good Ship Lollipop," Mooney and Vivian singing "Tiptoe Through the Tulips," Lucy playing "Glow Worm" on the saxophone, and Ethel Merman performing "Everything's Coming Up Roses."
Special Notes: This is the second-part of the two-part episode. Agnes is Ethel Merman`s real middle name. In the big finale, Lucy Carmichael plays "Glow Worm" on the saxophone. On I Love Lucy, Lucy Ricardo also played the sax and only knew one song: "Glow Worm."
