Dancing Queen was released by Swedish pop group ABBA in 1976 on their album Arrival, written by Benny Andersson, Björn Ulvaeus and Stig Anderson, with lead vocals by Agnetha Fältskog and Anni-Frid Lyngstad. It became a worldwide number one and one of the defining disco songs of the decade, later returning through films, musicals and countless dance scenes. Its instantly recognisable piano and chorus have kept it popular for generations, and short clips now circulate widely online whenever creators want a quick burst of joyful, nostalgic energy.
