Elton John Accused of Lyric Theft For 80s Song

The man behind the accusations -- named Guy Hobbs -- filed the lawsuit in Illinois federal court, claiming he wrote a song called "Natasha" back in 1982 based on his affair with a Russian cruise ship waitress ... and three years later, Elton jacked his idea.

According to the lawsuit, Guy copyrighted the song and circulated the lyrics to multiple publishing companies -- including Big Pig, which solely publishes Elton John songs -- but he never heard back.
