Does it make him jealous to hear a great song? Or at least competitive? "Oh, jealous, definitely! But I realise it's a young man or woman's work to write pop music," says Björn.
It is precisely this realisation that has led the band to decline numerous offers – some reportedly of up to $1billion – to. Björn believes that fans would ultimately be disappointed at the sight of four aged musicians on stage. But, given that they are a studio band first and foremost, I have often wondered why they don't record together. The prospect of an older, wiser Abba album is a tantalising one.
"It's difficult to talk about this because then all the news stories will be: 'Abba is going to record another song!'" says Frida. "But as long as we can sing and play, then why not? I would love to, but it's up to Björn and Benny."
Last year Agnetha said it was something she would also love to do. Could this be their last chance before – to paraphrase one of their own songs – time slips through their fingers? "Nothing's planned and it would have to be something very special," says Björn "But yes, why not?"
I love the fact that they know that this would set the world on fire if they were to do it. She even says "It's difficult to talk about this because then all the news stories will be: 'Abba is going to record another song!'"
