Off game: There was another link, which is, as I think, more believable:
Ivan The Terrible was a Russian Czar, better known for his violent and cruel behavior, and who was perfectly portrayed by Nikolai Cherkasov in Sergey Eisenstein's movie "Ivan The Terrible".
The music for the movie was composed by Sergey Prokofiev.
Among Prokofiev's other works, there is also "Peter And The Wolf", which Al and Wendy Carlos had succesfully parodied.
