No clue, but sounds like Boney M's Rasputin (also a great-but-obscure "trivia question" goes with that. lol.)
The only reason I knew it was I accidentally rediscovered that song a few years ago. I used to love it as a little kid for some reason. It was a case of "oh yeah! I remember this!", so I started researching the artist and its history. I mean, it's not often you hear a black dude singing about a Russian historical figure (who I was also mesmerized by as a kid after reading all the failed attempts at his life). Then, to top it off, he's dancing like a Russian on stage. Anyhoo... the "trivia". The guy who managed/created the group Boney M was also the guy who actually sang the song. The black guy dancing and getting all the notoriety as being the lead singer just lip-synced and danced on stage like he was on crack (seriously - I don't know how he kept that dancing up). But everybody I think knew he was lip-syncin'ing and wasn't the actual singer. Despite this, they were popular world-wide, including in Russia, from what I recall. Fast-forward to the days of Milli Vanilli who got torched and humiliated for hiding the fact they weren't actually singing or dancing on their hits. This is the trivia - the same guy who created/managed Boney M is the guy who created/managed Milli Vanilli. The irony is that the same thing he did with Boney M having the front men just be lipsyncers with someone else singing the actual vocals that made Boney M a worldwide hit is what crushed Milli Vanilli because they tried to hide it (I guess). The manager also went on to produce other songs/groups, like I think the gorup La Bouche (of "Be My Lover" fame) was created by him, too. Second bit of trivia I learned while researching Boney M back then. Their biggest hit was probably that song "Rasputin". The lead singer of Boney M died on the birthday of the actual historical figure Rasputin. I'm glad I finally got to use this bit of useless information in this off-topic post.
