Fast-forward to today, and ABBA are one of the most successful music groups of all time. The band was made up of two married couples: Agnetha Fältskog and Björn Ulvaeus, and Anni-Frid Lyngstad and Benny Andersson.

Both marriages broke down, resulting in the band's split in 1982. However, the four stars continued to make money through solo ventures and the Mamma Mia! musical franchise, which has delighted fans on both screen and stage for years.

After almost 40 years apart, the band reunited in 2021 to release new studio album Voyage. They’ve also launched a residency show in a custom-built arena in London, where 'de-aged' holograms (referred to as 'ABBAtars') of the famous quartet perform alongside a live band.

Individually, it's estimated that each member of the band is worth somewhere between $200 million and $300 million.
