Agnetha Fältskog’s extraordinary singing career began when she was only 15 years old. But in just two years she was knocking The Beatles off the top of the Swedish pop charts writing her own material. This new documentary features exclusive access to Agnetha in the studio and with her colleagues of both recent years and from ABBA, assessing and celebrating her journey as Sweden's 'girl with the golden hair'. This intimate and revealing programme features interviews with Björn Ulvaeus, Benny Andersson, Gary Barlow, Tony Blackburn, record producer Peter Nordahl, Jörgen Elofsson and Sir Tim Rice
