Parts of ABBA's upcoming Voyage concert setlist has been leaked

After almost four decades out of the spotlight, ABBA is about to make their return to the stage with a series of revolutionary virtual concerts at London's Queen Elizabeth Olympic Park in May.

Thanks to George Lucas' special-effects company, Industrial Light & Magic, holographic versions of Agnetha Fältskog, Anni-Frid Lyngstad, Benny Andersson and Björn Ulvaeus will perform with a live 10-piece band in the purpose-built arena.

But now parts of the beloved Swedish supergroup's setlist for the upcoming Voyage shows have been accidentally leaked.

According to The Sun, pictures from the band's rehearsal in Stockholm, including sheet music titles, were released by mistake.

The pictures were quickly deleted only a few minutes later, however, some eagle-eyed fans had already spotted some of the songs that will appear on the setlist.

It's claimed that as well as classic ABBA hits including 'Dancing Queen' and 'Gimme, Gimme, Gimme', the 22-song setlist will also include 'The Visitors', which opened the band's 1981 album of the same name – the last before their split and reunion.

The setlist also features the double-header of comeback songs 'I Still Have Faith In You' and 'Don't Shut Me Down'.
