Anderson/Ulvaeus

Björn Ulvaeus & Benny Andersson are the BB in ABBA, one-time husbands of Agnetha Fältskog and Anni-Frid "Frida" Lyngstad respectively. Björn started his career in Swedish folk group Hootenanny Singers, and Benny in the beat group Hep Stars, The. 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 reelase, 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.
