I Do, I Do, I Do, I Do, I Do
Written by Benny Andersson, Björn Ulvaeus, and Stig Anderson, this song from ABBA's third studio album takes inspiration from 1950s-70s European schlager music and Billy Vaughn's 1950s saxophone sound. It became ABBA's first number one hit in Australia, starting a 14-week chart-topping run, and reached number 13 on the US Billboard Hot 100, though it barely cracked the UK top 40.
