Rodgers & Hammerstein's Cinderella (1957, Kinescope)

''Cinderella,'' featuring Julie Andrews, was recorded on kinescope in Manhattan on March 17, 1957.
The final production, broadcast live two weeks later, was the only one written by Rodgers and Hammerstein expressly for television, and it was an enormous success for CBS, drawing 107 million viewers compared with the 65 million who watched ''Peter Pan'' on NBC two years earlier. [...]
In an article about ''Cinderella,'' TV Guide wrote, ''The viewer will thus have an opportunity to watch free of charge what most theatergoers would eagerly have paid many dollars to see on Broadway.''
