That Ain't Right

"That Ain't Right" was the 1942 debut single by The King Cole Trio. It was written by Nat King Cole and publisher, lyricist, and promotor Irving Mills. "That Ain't Right" hit number one on Billboard magazine's Harlem Hit Parade chart for one week. Although the song was the King Cole Trio's first successful single, it would be their final release for Decca, as the contract with the company expired before "That Ain't Right" became a hit.
