Over the weekend, ABBA gave their first performance together in three decades.

The move brought all four members of the legendary disco act together for the first time since 1986.

ABBA sung "Me and I," a hit of theirs from the 1980s, according to Sweden's Expressen.

Benny Andersson, Anni-Frid yngstad, Agnetha Faltskog and Björn Ulvaeus got together for a private event to celebrate the 50th anniversary of the group's founding.

The celebration took place on Sunday in Stockholm, Sweden.

The rendition was a bit of an impromptu affair.

It began with just the ladies of the group, but their male counterparts joined the song toward the end.
