"When Stalin says dance, a wise man dances."

I've been trying for some time now to find the original of this quote from N.S. Khrushchev's memoirs; it refers to an incident during Stalin's last years when the dictator ordered Khrushchev to dance the Gopak for some party officials. So far I've been unsuccessful; however, this evening I came across a 1958 dramatization by CBS TV entitled "The Plot to Kill Stalin", and to my surprise, it shows Khrushchev dancing the Gopak for Stalin. Khrushchev was at the height of his power in 1958, and wouldn't publish his memoirs until the late 1960's, so I wonder how CBS learned of the incident. Does anyone else find Oscar Homolka's portrayal of Khrushchev reminiscent of Londo Mollari?
