Bjorn and Benny composed all ABBA songs themselves. They had some help from manager Stig Anderson on some lyrics and Agnetha wrote one ABBA song with Bjorn called Disillusion. They recorded only 3 covers in Medley which was recorded for a charity album in 1975. Many songs were written on an island in the Stockholm archipello were both Bjorn & Agnetha and Benny & Frida had houses. In this early seventies pic ABBA is photographed on that island.
