Forming the group (1970–1973)
After the 1970 release of Andersson's and Ulvaeus' album "Lycka", two more singles credited to 'Björn & Benny' were released in Sweden, "Det kan ingen doktor hjälpa" ("No doctor can help with that") and "Tänk om jorden vore ung" ("Imagine if the Earth were young"), but clearly with more prominent vocals by Fältskog and Lyngstad – and with moderate chart success.
Fältskog released her fourth album in 1971 and married Ulvaeus on 6 July 1971. Andersson, Ulvaeus, and Fältskog started performing together on a regular basis at the Swedish folkparks during the summer of 1971.
The first signs of foreign success came as a surprise, as the Andersson and Ulvaeus single "She's My Kind of Girl" was released by Epic in Japan in March 1972, giving the duo a Top 10 hit. Two more singles were released in Japan, "En Carousel"(earlier version of "Merry-Go-Round") and "Love Has Its Ways" (a song they wrote with Koichi Morita).
