Mamma-MiaAbba members Benny Andersson and Bjorn Ulvaeus are said to be furious at the right wing Danish People’s Party after they have used their hit song Mamma Mia at their rallies paying homage to their leader Pia Kjærsgaard, changing the word Mia to Pia. (How droll – not!) Andersson, who last year donated a million kronor ($145,694) to aid the EU election campaign of Sweden’s Feminist Initiative, has reacted angrily to the Danish anti-immigrant party taking liberties with his copyrighted material commented saying, “They can bugger off,” The pair have now set their lawyers on to the case to stop the hate mongering anti-immigration party from using their happy little ditties.
