Since its release in 1976, ABBA’s song “Fernando” has been loved by fans around the globe, both for its sing-along chorus and its revolutionary spirit. In Fernando, Kay Dickinson takes readers from Sweden and Chile to Australia and Poland, tracing the complicated ways the song could express support with anti-capitalist and Third World liberation struggles while remaining an unrepentant commodity. A song about freedom fighters was unlikely to become a pop mega-hit, yet, as Dickinson demonstrates, ABBA’s lucrative, longstanding appeal rests on their ability to bridge contradictions within everyday life. Five decades later, “Fernando’s” rousing calls for freedom continue to resonate with gay liberation movements and other social struggles, demonstrating how a song can both be revolutionary and an envoy for global capital.
