The Four Seasons had a hit in 1963 with a song called "Walk Like a Man
," which prompted a lawsuit against Grand Funk. As a result, the title of Grand Funk's song was changed to "Walk Like A Man (You Can Call Me Your Man)."
As Bob Gaudio of The Four Seasons explained
, you can't copyright a title, but the Grand Funk song took it too far with the lyric "Walk like a man, and talk like a man."
