Story, 1977: Is ABBA going to split up?

What's really true about the rumour that the four members of ABBA don't get along that well anymore? Is it true that blonde Anna, now that's she is expecting a baby, doesn't feel like doing alle these performances any longer? What's true about the rumours that ABBA is going to split up?
Only recently, Björn (the one without the beard and Anna's husband) felt the need to answer all these questions. He said: "Of course we do have arguments from time to time. It so happens that we are four different personalities and we all have our mistakes and flaws. But we are very open, therefore we always talk things out right away. Indeed, Anna is pregnant but we planned that in such a way that no performances will be endangered. Anna is actually the group member who likes to perform most of all. And now the answer to the last question. Of course, ABBA is going to split up eventually. It's just not something for anyone to be concerned about just yet. Because we are only going to split up when people stop buying our records. All four of us know that that time will come eventually, but we hope that won't be any time soon."
