MUMBAI: Will the world get to be serenaded by Sweden’s global pop phenomenon ABBA again? Maybe.  Member of the legendary band Agnetha Faltskog, in an interview published by the German press has said she had not ruled out the possibility of reuniting the band's members for a concert.

"Perhaps a charity concert? I, at least, would not rule it out," the singer said. Faltskog is promoting her new solo album, "A", whose title was inspired by the fact that she was "one of the 'As' in ABBA".

The singer said she enjoyed listening to old ABBA hits, such as "The Winner Takes It All".

ABBA, formed by Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad, broke up in 1982 after years of cranking out hits. The group has sold some 378 million albums worldwide, outdone only by Elvis Presley and the Beatles.

They have repeatedly refused to reunite. “We will never appear on stage again,” Ulvaeus said in a 2008 interview. “There is simply no motivation to regroup. Money is not a factor and we would like people to remember us as we were,” he said.

The two male members-Ulvaeus and Andersson, however, have worked together on other projects, including "Mamma Mia", the hit musical and film, and the anthem for the 2013 Eurovision Festival, which will be held 14- 18 May in Malmo, Sweden.

If fans cannot taste the band’s reunion, they can enjoy the billion-dollar band’s legacy as the world’s first permanent ABBA museum, in capital Stockholm is set to open its doors on 7 May.

“We’re going to offer visitors a unique experience,” museum director Mattias Hansson said adding that they may even get a chance to speak live with a band member.

The museum will contain the band’s flamboyant 70s’ sequined costumes, gold records, and recreations of their recording studio and dressing rooms.

Fans who have dreamt of becoming the fifth member of the band will be able to appear on stage with the quartet and record a song with them thanks to a computer simulation.

Another room dedicated to the (band’s) song “Ring, Ring,” a 1970s telephone will be on display. Only four people know the phone number: ABBA members Agnetha Faeltskog, Anni-Frid (Frida) Lyngstad, Benny Andersson and Bjoern Ulvaeus, who may occasionally call to speak live with museum visitors.

The museum’s website says it expects to attract a quarter of a million visitors in 2013.

Tickets for the museum — which cost 23 euros, or $ 30 — are almost sold out for the first few weeks, going primarily to tourists from abroad.
