The entire country did not celebrate them but there were special broadcasts dedicated for ABBA at the national TV etc.
Perhaps not as widely known is that one of the ABBA figures (Benny Andersson) has composed and produced the famous musical named as Chess (together with Tim Rice etc.) so he is still going strong and am about the most important (and richest) person in Swedish music industry. Perhaps I should send him an email about Piano Society
Sounds,a good idea,,,we should let him know.
In australia, We liked ABBA, this is one of the modern band that does not die out just like Chopins music, I think its to do with the melody they wrote.
