The Abba phenomenon just goes on and on. The band were in the charts for nine years – but its two principal tribute bands have each now been together for more than a decade.

And the crowds are still on their feet by the end of the night at the Theatre Royal.

Voulez-Vous has a completely different approach to its 'rival' Bjorn Again – adopting a straightforward concert format (with 10 costume changes and a great light show) as opposed to a tongue-in-cheek look at the Scandanavian superstars.

It's the difference between a charicature and a portrait, an impersonation and an impression. So both have their own niche in the market. And both have that great font of hits on which to draw to make two hours rush past.
