The Legendary ABBA GOLD to re-unite

All four original members of Abba are to reunite for a new digital entertainment project.

The Swedish pop group have not formally performed together since they split up more than 30 years ago but did appear at a 50th anniversary party in June.

The project, which will involve virtual reality and artificial intelligence, has been described as a "new entertainment experience".

It will be developed in collaboration with music manager Simon Fuller.

"We are exploring a new technological world that will allow us to create new forms of entertainment and content we couldn't have previously imagined," Fuller said in a statement.

Full details of their new project will be announced in 2017.
