ABBA may have stunned their fans with their first songs in more than three decades - but the return of the pop quartet surprised the band members too it seems.
In an ITV News exclusive, Benny Andersson and Björn Ulvaeus said getting together with Agnetha Fältskog and Anni-Frid Lyngstad rekindled an instant chemistry.
