The "My Fair Lady" ensemble costumes were from the original 1957 Broadway stage production.
The television special's skeletal "Camelot" stage setting, including the drapery and banners, were relocated 'from' the Broadway theater stage - 'to' the NBC Brooklyn Studio for the segment.
The costumes were also from the Broadway production.
Richard Burton was 36 years old (b: 11/10/1925), in 1962, having departed the Broadway "Camelot" musical shortly after this television special had been taped in late November, in the fall of 1961. Burton was preparing to depart for his co-starring role with Elizabeth Taylor in the 20th Century Fox Film "Cleopatra" filming in Rome.
Founded by John Kenley, "The Kenley Players" Equity Summer Stock Theatre Company provided productions featuring Broadway, film, and television personalities in the Western-mid-belt cities. The summer stock network of theaters included Dayton, Akron, the largest populated city of Columbus, Warren, (Ohio), and Flynt, (Michigan). Robert Goulet, (with his wife Carol Lawrence), appeared in productions including "Man of La Mancha" (1959), "Pajama Game" (1959), "Belles Are Ringing" (1959), "Dream Girl" (1959), "Meet Me In Saint Louis" (1960), Rogers and Hammerstein's "South Pacific" (1960), "Carousel" (1960) when Robert Goulet performed the role of Billy Bigelow. In the late summer of 1959, Robert Goulet was introduced to librettist Alan Jay Lerner and composer Frederick Lowe, who were having difficulty casting the role of "Lancelot" for their stage musical production of "Camelot." Impressed by Goulet's voice and talent, Lerner and Lowe signed the virtual newcomer to perform the role opposite Richard Burton (King Arthur) and Julie Andrews (Queen Guenevere). "Camelot" the musical opened in Toronto, Canada, in October, 1960.
