Björn Ulvaeus & Benny Andersson

[a=Björn Ulvaeus] & [a=Benny Andersson] are the BB in [a=ABBA], one-time husbands of [a=Agnetha Fältskog] and [a=Anni-Frid Lyngstad] respectively. Björn started his career in Swedish folk group [a=Hootenanny Singers], and Benny in the beat group . They wrote their first song together in June 1966, "Isn't It Easy To Say", which was recorded by the Hep Stars. Their first and only album as a duo was released in 1970, and this was the first album to feature both Björn, Benny and their partners. A song from the same period, "She's My Kind Of Girl" became a major success in Japan in 1972, and this was an early sign that the group had what it takes to make it internationally. Björn & Benny have writing and production credits on virtually every ABBA release, and after ABBA they went on to write the musicals "Chess" and "Kristina från Duvemåla", and write and produce for many Swedish and European artists.
