2004 marks the 30th anniversary of Abba's victory for Sweden in the 1974 Eurovision Song Contest in Brighton. To commemorate this event, UK's ITV channel will broadcast this Tuesday a documentary where Abba open their hearts and talk about those (happy or sad) days.

The EBU paid a tribute to Abba's 30th victory anniversary last May, during the Eurovision Song Contest's semi-final in Istanbul with The Last Video. Now, British channel ITV joins the celebrations, by broadcasting this Tuesday a special documentary, which tells the true story of Abba (at least it seems like it), by the band's members themselves.

The most profound confessions will probably be made by the blonde star of the band, Agnetha Faltskog, who is portrayed as the main reason why the band never re-united or ever made a comeback, despite the molti-million pounds offers they got throughout the years. 'I felt as if they would get hold of me and I would never get away again. There is not a day goes by that I don't think about Abba, dream about Abba. It was both good and bad, fun too, but I wouldn't do it again', says Agnetha in the film. She also denies the rumours of her being a recluse, confining herself to her home on a tiny island near Stockholm, but admits she suffers from flights phobia, laying part of the reason for not re-uniting on it.

The 90 minute film on ITV will not only feature Agnetha. The film crew followed Bjorn Ulvaeus, Benny Andersson and Anna-Frid Lyngstad – known as Frida – in the run-up to the fifth anniversary of the hit West End musical Mamma Mia, which is based on Abba hits. The members confess on the occasional rivalries between the two leading ladies in the band, about the break up of the married couples and the effect it had on the four as a touring band.

The documentary film, Super Troupers – 30 Years Of Abba, this Tuesday, 9.00pm, on ITV.
