ABBA holograms sticking around?

The holograms of ABBA's members could stick around long after headlining seven months of shows in London.

“If you are an ABBA fan, who loyally has stuck with us for many years, our hope is that you will see the ABBA-tars as agents in the new story, which may lead to exciting new things in the future,” the Daily Star newspaper quoted the Swedish group as saying.

Fans speculated that they could be involved in anything from pop-up musical projections to ads.
