Russia,

There lived a certain man in Russia long ago

He was big and strong, in his eyes a flaming glow

Most people looked at him with terror and with fear

But to Moscow chicks he was such a lovely dear

He could preach the Bible like a preacher

Full of ecstasy and fire

But he also was the kind of teacher

Women would desire

Ra ra Rasputin

Lover of the Russian queen

There was a cat that really was gone

Ra ra Rasputin

Russia's greatest love machine

It was a shame how he carried on

He ruled the Russian land and never mind the Czar

But the kazachok he danced really wunderbar

In all affairs of state he was the man to please...
