And backwards...
ABBA has never officially announced the end of the group, but it has long been considered dissolved.
I wonder if the statement below (from Wikipedia) could have applied to the Beatles if Paul had never made his announcement.
Bugs me all this re-uniting rubbish, (like with the Beatles) it would never be as good, and just for commercial reasons ie $$$$$$$I admire Agnetha in that interview Barry when she says 'get back together for what, we did it all'some bands should stay away from re-uniting, everything was done when they were together
