Stockholm - The Swedish pop quartet Abba plan to get together after 25 years on Friday for the premier of the film Mamma Mia! in Stockholm.

But the four will be attending the screening of the Hollywood version of the Abba hit-musical starring Meryl Streep and Pierce Brosnan as members of the audience.

A spokeswoman for film distributer UIP told the Sweden's Aftonbladet newspaper that ex-Abba singer and songwriter Benny Andersson, 61, and Bjorn Ulvaeus, 63, wanted to appear alongside Singer Anni-Frid Reuss-Lyngstad, 62 and Agnetha Faltskog, 58 at the gala premier.

Streep and Brosnan wanted the film, which has already premiered in London and Berlin, to also premiere in Abba's home country. Because of Faltskog's reclusive lifestyle, the reunion was still not certain.

In 2004, the singer pulled out at the last minute of a performance to mark the 30 years since the group's won Eurovision Song contest in Bristol with the hit Waterloo. Abba broke up in 1982. (dpa)
