Stalin heard a performance of Mozart's Piano Concerto No. 23 on the radio performed by Yudina and asked for a copy. It was a live broadcast so officials woke up Yudina, drove her to a recording studio where a small orchestra had quickly been assembled, and made her record the concerto in the middle of the night, a single copy was pressed from the matrix and then presented to Stalin (the matrix has survived and the recording has been available on CD). It is said that he broke out in tears after hearing only the first notes of Yudina's playing.
