In 1972 a Swedish group was formed. It was called ABBA.
After one unsuccessful attempt in the Swedish National Final they got the golden ticket to the Eurovision Song Contest 1974, and their world, along with that of the contest, was changed beyond recognition.
Eight years later they agreed to take a break but, rather than temporary, that became a permanent one. The only time that they were seen together was in a video, shown at the Eurovision Semi Final 2004 in Istanbul. Even then the performers were puppets and during the recording of their ‘human’ appearances the four real members weren’t actually all there at the same time.
We took a break in ’82, and it was meant to be a break. It’s still a break and will remain so. You’ll never see us onstage again. We don’t need the money, for one thing. Usually the reason bands have reunions is that one of them is destitute and the others want to help. Fortunately that has not happened to us.
There have been several speculations that ABBA would reform and, as recently as in 2013 Agnetha had intimated that it could be for the fortieth anniversary of winning the Eurovision Song Contest. Nothing happened.
NME’s article continues:
In 2008, Andersson and Ulvaeus again vowed not to reform, and turned down an alleged $1 billion offer in 2000 to tour.
To the disappointment of their enduring fans it looks less and less likely that we will see it happen.
