Abba reunite for Swedish film premiere

The four members of legendary pop supergroup Abba reunited for the first time in 22 years on Friday at the Swedish premiere of movie musical 'Mamma Mia!'.

Bjvrn Ulvaeus, Benny Andersson, Anni-Frid Lyngstad and Agnetha Fdltskog joined the film's stars, including Meryl Streep and Pierce Brosnan, at the Stockholm screening, much to the delight of the band's diehard fans - many of whom had camped out for several hours.

'Mamma Mia!' brings the hits of the legendary 1970s group to life on the big screen and is based on the stage production of the same name.
