London’s Tate Modern hosts 40th anniversary celebration of ABBA

London’s Tate Modern gallery was the scene of a huge party marking the 40th anniversary of legendary Swedish pop group ABBA’s first international hit, “Waterloo.”

ABBA Benny Andersson, AnniFrid “Frida” Lyngstad, Bjorn Ulvaeus and Agnetha Fältskog won the Eurovision Festival in Brighton with “Waterloo” on April 6, 1974.

The band charted with huge hits like “Fernando,” “Mamma Mia,” “Dancing Queen” and “Thank You For the Music,” with Frida and Agnetha, who were married to Benny and Bjorn, respectively, harmonizing perfectly.

The group was successful because of “the combination of the four of us, the talent of the composers and the two beautiful voices together, that’s a good combination for success,” Lyngstad told Efe.

The group cranked out hit after hit during their 19721982 run, selling more than 380 million records.

“It is incredible that ABBA is still relevant today because the people still listen and its songs continue playing,” Bjorn said.

The two couples, who are no longer married, last performed together on a television show in 1982.

Bjorn and Frida walked the red carpet together at the Tate Modern on the banks of the Thames River on Monday night as a mob of fans cheered.

Andersson, who composed most of the group’s songs, celebrated the anniversary on Sunday night in Stockholm.

He and Fältskog did not attend the party in London.

Fans have long clamored for the group to reunite, but it appears unlikely for the divorced foursome.

“It is very hard because Benny and Bjorn are busy with other things and we are older and do not have the motivation,” the 69yearold Frida said.

The four still remain friends even though they no longer perform together, Bjorn said.

“Sure, we are all very good friends,” Bjorn said, smiling.
