"Say It Ain't So, Joe" is a song written and performed by the English actor and singer Murray Head.

He wrote the following comment in the liner notes when he re-released the song on the compilation album, When You're in Love (1995): "Say It Ain't So, Joe" was provoked by a seventies documentary on Richard Nixon prior to his resignation.

The presenter was asking the editor of a small town newspaper outside Washington, how, in the face of conclusive evidence and proof, his readers could still show such undying support for the president they elected.

The editor likens the situation to a scandal in the twenties, when [Shoeless] Joe Jackson, the famous baseball player, was rumoured to have taken a bribe to sink his team in the final of the World series.
