Björn Ulvaeus leaves a small opening for an ABBA performance next year when he visits Morgonstudion and is asked if it is not time for a reunion 50 years after the Eurovision win.

"It's almost a bit weird, isn't it? That it is precisely in Sweden, just this year. And it's just happened so we don't really know. There are many who think "what can you do for something fun?"

It sounds like it's open?

"Yes, I'm just speaking for myself. I absolutely cannot speak for the others," he says.

ABBA colleague Benny Andersson, on the other hand, has been clear that he will not perform on a Eurovision stage again.

–No! Seriously – no, he replied in an interview with the BBC on May 25 this year.
