"Two for the Price of One" is a song recorded by Swedish pop group ABBA, featured on their 1981 album The Visitors.
The Leader-Post explains that the song is about "our pathetic love-starved hero answering an ad for the girl of his dreams".
[2] The song's lyrics describe a male custodian answering a personal ad for two women seeking a threesome, until the final punchline which reveals that one of the women is the other one’s mother, not revealing whether the mother is just an intrusive chaperone or if the original innuendo still stands.
[3] Keith Tuber of Orange Coast Magazine describes the song as his favourite on the album, describing it as a "humorous, clever ditty with a twist ending", and likens it to Rupert Holmes' "Escape (The Piña Colada Song)".
In regard to the song's inclusion on ABBA's live album, it says "if you're gonna have one really really bad ABBA song on a live album, at least make it something goofy from the early days, like "King Kong" or "Nina Pretty Ballerina"!
