ABBA reunites for first performance in 30 years in honour of their 50th anniversary

They came together, and they sailed. Their music is still celebrated by people all over the world.

It has been 30 years since the members of ABBA performed together - until now.

The disco group joined forces on Sunday as they celebrated the date that Björn Ulvaeus, 71, and Benny Andersson, 61, first met 50 years ago, according to Expressen.

To mark five decades of friendship, the pair apparently threw a private party at Berns Salonger in downtown Stockholm.

The remaining members of the group Anni-Frid 'Frida' Lyngstad, 70, and Agnetha Faltskog, 66, were also at the bash.

The two women are said to have dedicated a performance of their 1980 song Me and I to the men, who then decided to join them on stage and perform with them.

It marked the first time the four-piece had all performed together since 1986.

The band broke up in 1982, and were last seen together at the opening of Mamma Mia! The Party back in January.

Björn and Agnetha were previously married from 1971 to 1980, while Benny and Frida also divorced in 1980 after marrying in 1978.

ABBA, who are one of the most famous and successful bands of all time, released a slew of hits throughout the 1970s and early 1980s.

In 1974, they won the Eurovision Song Contest with Waterloo.
ABBA's songs were used as the base of jukebox musical Mamma Mia!, which debuted in 1999 and has grossed over $2billion worldwide.

In 2008, it was adapted into a movie of the same name, starring Meryl Streep, Pierce Brosnan, Colin Firth, Amanda Seyfried, Dominic Cooper and Julie Walters.
