Ulvaeus , Andersson and Stig Anderson believed in the possibilities of using the Eurovision Song Contest as a way to make the music business aware of them as songwriters , as well as the band itself . In late 1973 , they were invited by Swedish television to contribute a song for the Melodifestivalen 1974 and from a number of new songs , the upbeat song " Waterloo " was chosen ; the group was now inspired by the growing glam rock scene in England
