ABBA unhappy about 'Mamma Pia!'

STOCKHOLM, Sweden, Sept. 23 (UPI) -- Lawyers for Benny Andersson and Bjorn Ulvaeus have warned the conservative Danish People's Party not to use an ABBA song to celebrate their leader.

The Local said the political group changed the lyrics of "Mamma Mia!" to "Mamma Pia!" in honor of Pia Kjaersgaard without ABBA's permission and used it at rallies and other political events.

Andersson and Ulvaeus, who were original members of the iconic pop band, have told their attorney to sue the party if they don't stop using the song immediately.

"They can bugger off," Andersson told the news agency TT Spectra. "Firstly, you cannot just re-write songs as you like and secondly we want them to understand that we have absolutely no interest in supporting their party.

"ABBA never allows its music to be used in a political context. This is something that we have pointed out to the Danish People's Party," Andersson added.
