Abba's 'Waterloo' voted best Eurovision song of all time

BBC viewers have selected Abba's 'Waterloo' as the greatest Eurovision song of all time. The Swedish foursome won it in 1974 in Brighton, and the track went on to sell nearly 6m copies. This year's competition was cancelled in March amid the coronavirus pandemic. None of the 2020 songs will be carried over to next year. Instead, countries will select new entrants for the 2021 contest.
