Swedish supergroup Abba announced its first new album in four decades on Thursday (Sept 2) and said it would stage a series of virtual concerts using digital avatars of the members in London next year.

Fans piled online to celebrate the long-awaited reunion of one of the world's most successful bands. "2021 has been saved by new Abba music," @elliemiles23 said in one widely shared Twitter post.
