Johnny Farnham's first commercially successful solo recording was the novelty song entitled "Sadie (The Cleaning Lady)", his manager Darryl Sambell had disliked it as the lyrics were so persistent. However, EMI's in house producer, David Mackay, insisted and so the single was released in November 1967. By arrangement with Sambell, Melbourne radio DJ Stan Rofe pretended that he disliked "Sadie" before playing it. Rofe continued the ploy on TV's Uptight and viewers responded with calls to play the song. Rofe was also a writer for Go-Set, a teen-oriented pop magazine, another writer for the magazine, Ian Meldrum, praised Farnham's efforts. "Sadie" hit #1 on the Go-Set National Singles Charts in January 1968 and remained there for five weeks. Selling 180 000 copies in Australia, "Sadie (The Cleaning Lady)" was the highest selling single by an Australian artist of the decade. Farnham's second single, released in March, was the double A-sided "Underneath The Arches" (non-album track) / "Friday Kind Of Monday", which peaked at #6. The album, Sadie, produced by Mackay was released in April.
