Recorded on this day in 1975 during a session with the band at Stockholm’s Metronome Studio (today Atlantis) and generally bundled with the b-side the instrumental “Intermezzo № 1,” “Hey, Hey Helen,” or “Tropical Loveland” to illustrate their musical variety and originally offered to the British pop group Brotherhood of Man to produce and perform—who turned it down, the lead single from ABBA’s eponymous third studio album was an international hit when released later in September of the same year. Despite its global acclaim and reception, it is ABBA’s seventh most popular song.
