The two special episodes to feature Ethel Merman ("Lucy Teaches Ethel Merman to Sing" and "Ethel Merman and the Boy Scout Show") were originally just one episode, "Lucy Teaches Ethel Merman to Sing". This installment was a consolation prize to Merman after her Desilu-produced pilot, "Maggie Brown", was rejected as a regular series by CBS. The plot was much as it remains today with Lucy and Viv trying to pass off Agnes Schmidlap as Ethel Merman, not knowing that it really is Ethel Merman, and Lucy attempts to teach her how to sing. In the original version, Lucy's voice lesson scene with Merman (which was lifted from the previous season's episode "Lucy's Barbershop Quartet" in which Hans Conried was the instructor and Lucy the pupil) was much shorter than it is today and that episode ended with the Boy Scout show, with Jerry Carmichael hosting, Sherman Bagley dancing, and Lucy joining Ethel for a brand new version of Merman's great hit "Anything You Can Do (I Can Do Better)". But then, Desilu Productions thought that maybe too much had been crammed into one half-hour and since Ball and Vance (who both were great friends of Merman) were having such a marvelous time working with the legendary Broadway belter, they decided to expand it into two episodes, thereby taking advantage of Merman's formidable talents. So, a second filming was scheduled. In Part 1, Ethel was to be the houseguest of Lucy and Viv for a few weeks, and then in Part 2, a full blown episode was created that included scenes of Lucy once again, trying to get into the act. An all new Boy Scout show was filmed also, with Jerry once again hosting, Sherman dancing, and Lucy, Viv, and Ethel, this time joined by Mr. Mooney, singing and dancing through a history of show business.
