Петя и волк
Prokofiev, while touring the West in 1938, visited Los Angeles and met Walt Disney. Prokofiev performed the piano version of "Peter and the Wolf" for ""le papa de" Mickey Mouse", as Prokofiev described him in a letter to his sons. Disney was impressed, and considered adding an animated version of "Peter and the Wolf" to "Fantasia", which was to be released in 1940. Due to the war, these plans fell through, and it was not until 1946 that Disney released his version of "Peter and the Wolf". It is not known if Prokofiev, by that point behind the Iron Curtain, was aware of this.
