Um....

An episode of a tv show I was watching included a live video version of the song Rasputin by Boney M and my brain broke.

For... reasons (?) I think I have always assumed that song was an ABBA song and now I've spent a bit too much time trying to figure out what ABBA song I may have confused with this particular song?  The internet suggests "Gimme, Gimme, Gimme" as a "sound-alike" but I feel like ABBA had some song about, I dunno, the same thing?  Or certainly... lovers?

Y'all?  I know I'm not the only one who has made this mistake (like thinking a certain horse song was a Neil Young song when it was actually an America song...) but my brain is refusing to give up on the idea that there is a song about a Russian someone or other that was an ABBA song.

Am I completely wrong?  Help?!
