where the members of abba married to each other
ABBA During the band's active years, Fältskog & Ulvaeus and Lyngstad & Andersson were married. At the height of their popularity, both relationships were suffering strain which ultimately resulted in the collapse of the Ulvaeus–Fältskog marriage in 1979 and the Andersson–Lyngstad marriage in 1981. These relationship changes were reflected in the group's music, with later compositions featuring more introspective and dark lyrics in contrast to their usual pure-pop sound.[8]
