This up-tempo tune from the Voulez Vous album found songwriters Bjorn Ulvaeus and Benny Andersson updating their love for 1950s-era rock & roll to fit the style of 1970s dance music. The lyrics, which chastise a girl who's a little too eager to become a woman, have a macho swagger worthy of an early-'60s Elvis Presley single. This macho feel is enhanced by a rockabilly-styled melody that flowers into a swinging chorus. However, a purely ABBA-esque pop element makes itself felt on a post-chorus bridge whose dainty, singsong feel adds a bit of pure ear candy to offset the song's otherwise rocking feel. It's the kind of song that would have been effective if done in a purely rock version, but ABBA's recording balances the song's rock elements with dance music touches to create an intriguing dance/rock hybrid: the chugging guitar riffs and the wild saxophone lines on the chorus uphold the song's rock element but tight, cymbal-heavy drum work and programmed synth lines give it a disco shading that makes it quite danceable. The resulting song became an international dance-floor favorite, but its rock & roll edge is strong enough that it would work just a well as a stripped-down rocker.
