"Sadie (The Cleaning Lady)" was Australian pop singer Johnny Farnham's first solo single.

The song was written by United States writers Ray Gilmore, Johnny Madara and Dave White.

Sambell also arranged for the electrical appliance store Godfreys to supply a vacuum cleaner salesman, a Mr Jolly, to be on hand.

[7][12] By arrangement with Sambell, Melbourne radio DJ Stan Rofe pretended that he disliked "Sadie" before playing it.

[13] According to author Jeff Jenkins, another local pop performer, Mike Furber, had the first option on recording "Sadie", but declined.
