This program was originally broadcast in color but it was preserved in black and white because at the time of broadcast, videotape did not exist. It was preserved by Kinescope which was a film camera placed in front of a Black and white television set in order to film the images.
For a long time, this version of the musical was thought to be a lost film, a victim of the lack of preservation of many early television broadcasts. By chance, a copy of the master reel was found in the home of a retired executive for Alcoa, and restored for a DVD release, distributed on November 29, 2011.
