Thank God there's at least one legendary band sensible enough not to want to taint their legacy - the members of ABBA have said that they will never reform.

And although the pop quartet are currently pimping the film version of the musical based on their songs, 'Mamma Mia!', members Bjorn Ulvaeus and Benny Anderson have said there is 'no motivation' to reform.

All four members appeared together for the first time in years at the weekend for the Swedish premiere of the film, where Ulvaeus said: "We would like people to remember us as we were: young, exuberant and full of ambition. I remember Robert Plant saying Led Zeppelin were a covers band now because they cover all their own stuff. I think that hit the nail on the head."
