ABBA Reunites at Stockholm Restaurant

— -- It's been years since Swedish group ABBA joined forces for a public event, but the four members reunited for the opening of former bandmate Björn Ulvaeus' new "Mamma Mia"-themed restaurant in Stockholm. The restaurant, which offers food and entertainment, is based on the Greek taverna in the movie.

Ulvaeus and the other three former members of the group - Agnetha Fältskog, Benny Andersson and Anni-Frid Lyngstad - split in 1982 after five very successful years.

As the four took the stage inside the restaurant Wednesday night, fans applauded the former hit group. Lyngstad even threw her hands in the air, overtaken by the excitement. Before the big party, ABBA also walked a red carpet and spoke to reporters.

“We are here to party,” Ulvaeus said, according to the Guardian.

Sadly, the former group did not perform.
