This Swedish pop group won the 1974 Eurovision Song Contest in Brighton and celebrated in the Napoleon suite of the Grand Brighton Hotel. Thirty years later, at the semi-final of Eurovision 2004 in Istanbul, all four members made cameo appearances in a comedy interval video. Which group is this?

Question

Accepted Answer

ABBA. ABBA's 1974 Eurovision win with Waterloo launched them into international superstardom. The Grand Brighton hosted their post-victory celebration, and the group's brief 2004 reunion cameo in Istanbul was one of their few public appearances together after their 1982 split.
