Does Your Mother Know

Written by Benny Andersson and Björn Ulvaeus for ABBA's sixth studio album Voulez-Vous, this track is notable as one of the group's few songs to feature Ulvaeus as lead vocalist rather than Agnetha Fältskog or Anni-Frid Lyngstad. The single reached number one in Belgium and the top ten in eight other countries, with Ulvaeus later stating it would have been a bigger hit if Fältskog or Lyngstad had sung lead.
