In late 1974 Andersson , Ulvaeus and Anderson were invited by Sveriges Television as composers to submit a song to the 1975 '' melodifestivalen '' . Since ABBA themselves did not want to compete in the contest again , just one year after having won , they instead gave the opportunity and the song to Polar Music labelmates Svenne & Lotta . " Bang-A-Boomerang " was given new Swedish lyrics by Stig Anderson and retitled " Bang en Boomerang " and the duo subsequently made a vocal recording of the track in November 1974 - produced by Björn & Benny - with a different arrangement , most noticeably slightly shorter ( 2:50 ) than the original demo , to fit the Eurovision three-minute rule . The song finished 3rd in the Swedish preselections in February 1975 , became one of Svenne & Lotta 's biggest hits and spent 7 weeks on the Svensktoppen radio chart during the period 9 March-11 May 1975 , with a 2nd place as best result . Svenne & Lotta also recorded the song with the original English lyrics , both versions were included on their 1975 album '' Svenne & Lotta 2/Bang-A-Boomerang '' ( Polar POLS 259 ) . The English version was also released as a single in Denmark and became a big seller there , from a Scandinavian perspective the track is therefore still primarily seen as a hit single and Melodifestivalen classic by Svenne & Lotta . Under the name of " Sven & Charlotte " , their original English version was also released in most European countries , and in Oceania , charting in several
