Everyone's favorite two-hit wonder -- a-ha -- is set to perform at London's Royal Albert Hall on May 24.

(A little insider joke there between me and the 10-million a-ha fans out there who were ready to kill me last year when I called them a one-hit wonder.)

To make matters more confusing, the event isn't being billed as an "a-ha concert." Rather, it's formally called "An Evening With Morten Harket, Savoy & Magne F." And yes, for those keeping score, those are the only three members of the band.

"We cannot promise that these three artists will join forces, as they have been known to do on other festive occasions around the world," the band's official website says. "But there is widespread speculation within the organization of some sort of special appearance."

Instead, fans can expect performances for their individual solo careers. But beyond that? "If you expect to see a regular show by the musical group known as a-ha," the website continues, "we kindly ask you to wait for the next scheduled performance convenient to your location."

So all three members are there, at the same time, at the same venue. And the band is still technically together. But don't expect any a-ha songs? Are you kidding me?
