The story of the Romanov family seems tailor-made for Hollywood (and Hollywood has embraced it, many times) with fabulous wealth and power, war and revolution, personal heartaches, conflicts, romance, deception, and action -including chase scenes. Parts of their history would be considered too unbelievable if it were presented as fiction. For example, the Russian royal family's advisor Rasputin was a strange character in life and even more so in death.
But there must be more to the song, because Rasputin wasn't quite dead even after he was shot! Read what really happened to Rasputin, and to the Romanovs at Atlas Obscura. Link
Ra ra Rasputin/Lover of the Russian queen/They put some poison into his wine/Ra ra Rasputin/Russia's greatest love machine/He drank it all and said "I feel fine"
Ra ra Rasputin/Lover of the Russian Queen/They didn't quit, they wanted his head/Ra ra Rasputin/Russia's greatest love machine/And so they shot him till he was dead

Quite the coincidence.
