Before ABBA (1969-1972)
Andersson met Björn Ulvaeus in June 1966, and the two started writing songs together, their first being "Isn't It Easy To Say", eventually recorded by The Hep Stars. He also had a fruitful songwriting collaboration with Lasse Berghagen, with whom he wrote several songs and submitted "Hej, Clown" for the 1969 Melodifestivalen - the Swedish Eurovision Song Festival finals. The song finished in second place. During this contest he met vocalist Anni-Frid Lyngstad, and they soon became a couple. Around the same time his songwriting companion Ulvaeus met vocalist Agnetha Fältskog.
The personal relationships and Andersson and Ulvaeus' songwriting collaboration has led quite naturally to the very close co-operation which the four friends had during the following years. Benny and Björn scored their first hits as songwriters in the spring of 1969: "Ljuva Sextital" (a hit with Brita Borg) and "Speleman" (a hit for The Hep Stars). As the two couples began supporting each other during recording sessions, the sound of the girls' voices convinced the songwriters to model their 'group' on the like of MOR acts Blue Mink, Middle of the Road and The Sweet. Thus, ABBA came to life.
