Abba comeback: band announce 'revolutionary' concert and brand-new album – video

The Swedish pop quartet Abba have reunited after 40 years for Voyage, an album of new songs set for release on 5 November. The group – Benny Andersson, Agnetha Fältskog, Anni-Frid Lyngstad and Björn Ulvaeus – have also announced a new concert experience in London. Digital versions of themselves (not holograms, their team insisted) will appear nightly alongside a 10-piece live band at a new 3,000-capacity venue in the city’s Olympic park, called the Abba Arena
