Ann sang with Muddy's band. "Mojo" had not yet been released, but in spite of Sol Rabonowitz's warning not to sing unreleased material, Ann taught Muddy's band the song and performed it regularly during the tour. Muddy liked the song so much that he asked Leonard Chess to let him record it himself. Chess, who didn't know anything about the Ann Cole recording, gave the Waters record a rush release and both versions came out in the same week. The difference in the lyrics between the two versions resulted from Muddy's inability to remember the original words (written by Preston Foster). Waters claimed to have written the song. Eventually the matter went to court, where it was ruled that Foster was the composer. But the two versions are still separately copyrighted.
