The members of Swedish supergroup ABBA are talking about having a reunion in 2014 to celebrate the 40th anniversary of "Waterloo," the band's first big hit, Agnetha Fältskog, one of the group's two vocalists, said in an interview published by the German newspaper Welt am Sonntag on Sunday.

"We are thinking about it a lot," Fältskog said in response to a question about a possible return to the stage by the group.

"In April 2014, it will be 40 years since we won the Eurovision Festival in Brighton with 'Waterloo,' and there are some good plans to do something to mark the anniversary," the 63-year-old singer said.

There is no telling whether the plans will come to fruition and it is best to just let things take their course, Fältskog said.

Benny Andersson, Anni-Frid Lyngstad, Bjorn Ulvaeus and Faltskog cranked out hit after hit during their 1972-1982 run, selling more than 380 million records.

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

In May, a museum dedicated to ABBA, the most popular Swedish group of all time, opened in Stockholm.

Ulvaeus is the principal investor and runs the company that controls "ABBA The Museum," which charges an admission fee of 195 Swedish kronor (about $30) and expects more than 200,000 visitors annually. EFE
