Bjorn says Abba reunion is too big to contemplate

Exhibition: Bjorn Ulvaeus

Abba star Bjorn Ulvaeus said the pop group will never perform again because it would be "too enormous" - as he unveiled a show charting the rise of the band against the backdrop of "grim" 1970s Britain.

The immersive exhibition at London's Southbank Centre takes visitors inside a dark and dreary British living room, a recreation of the Brighton hotel bedrooms the band slept in following their stunning Eurovision win, a recording studio and an aeroplane cabin.

Ulvaeus (72) said the exhibition made him realise how "impossibly gloomy" Britain was at the time, with a collapsing economy, a three-day working week, and strikes.
