Years Active: 1972 - 1982
Members: Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson, Anna-Frid Lyngstad
Biggest hits: 'Dancing Queen', 'Fernando', 'Waterloo' and 'Mamma Mia'
Studio Albums: 8
Albums sold: 300-400 million worldwide
Legacy: Since their split, the ABBA brand has continued spawning the successful stage musical, 'Mamma Mia' and then the film in 2008. They are the second best-selling music group of all time (behind the Beatles)and they were inducted into the Rock N' Roll Hall of Fame in 2010.
Reason for split: The band were made up of two couples - Agnetha and Bjorn, Frida and Benny, however fame put a strain on both relationships and they ended in divorce. This killed their creative mojo as a group and they split shortly after.
Net Worth: There are no exact figures but they are estimated to have a net worth of £100m each. Let's not forget that in 2008 they turned down an offer of $1bn to tour again, so they must not be strapped for cash!
Years Active: 1967 - Present
Members: John McVie, Stevie Nicks, Lindsey Buckingham, Mick Fleetwood Mac
Biggest hits: 'Dreams', 'Don't Stop', 'The Chain' and 'Go Your Own Way'
Studio Albums: 17
Album sold: 100 million worldwide
Legacy: They are one of the best-selling bands of all time, they were inducted in to the R&R Hall of Fame in 1998 and have also received a Brit Award for Outstanding Contribution to Music. In 2015, they headlined the Isle of Wight festival.
Reason for split: The band went through many line-up changes and similar to ABBA, for some time there were two couples in the group (Buckingham and Nicks, Christine and John McVie) which caused a lot of strain but also produced their most successful album, 'Rumours'. They returned to the most-famous line-up in 1997 and have been touring since.
Net Worth: The group has a net worth of approximately £85m (www.celebritiesmoney.com)
