Fans of one of the biggest music groups in the 1970s would be happy to know that Swedish group ABBA is considering a reunion to celebrate 4 decades of their win in the Eurovision Song Contest in 1974 when they performed Waterloo.

The song, their group's first single, was responsible for the global fame the group attained. For 10 years, ABBA ruled the charts with hit songs such as Mamma Mia, Dancing Queen, Fernando and Take a Chance on Me.

Their last performance as a quartet was on Dec 12, 1982, at the British programme The Late, Late Breakfast Show, after which the four members pursued solo careers.

In 2008, the group reunited for the hit movie Mamma Mia.

However, Agnetha Faltskog, now 63, could not yet provide more details of the reunion. ABBA was formed in 1972 and the name was the combination of the first names of its four members, Agnetha, Bjorn Ulvaeus, Benny Andersson and Anni-Frid Lyngstrad. They were initially couples, but both pairs eventually separated.

ABBA sold more than 380 million albums and singles globally.
