Benny Andersson and Bjorn Ulvaeus merged Phil Spector's wall-of-sound grandeur with driving glam-rock guitars and boogie-woogie piano riffs. Agnetha Faltskog and Anni-Frid Lyngstad deliver tight octave harmonies that interlock with brisk saxophone fills, turning a tongue-in-cheek historical metaphor into an exhilarating Eurovision triumph.
