Synopsis by Hal Erickson
In the conclusion of a two-part story, Broadway legend Ethel Merman has agreed to perform in the Boy Scout variety show. Eagerly looking forward to sharing the stage with La Merman, Lucy (Lucille Ball) and Viv (Vivian Vance) are crestfallen when their Boy Scout sons arrange for the two ladies to remain offstage as wardrobe mistresses. Suffice to say that everyone--even Mr. Mooney (Gale Gordon!--gets into the act before the final curtain. Ethel Merman sings "Everything's Coming Up Roses", Vivian Vance performs "On the Good Ship Lollipop", Gale Gordon warbles "Tiptoe Thru the Tulips", and the whole cast joins in for the finale, "There's No Business Like Show Business".
