"If I can contribute in any way to making it go well, I want to do it. I don't think so, but I'll do it anyway," Benny Andersson tells TT.
Are you a Social Democrat?
Yes. And my grandfather, and my father.
Andersson says he usually tries to avoid being a "crowd-pleaser".
But this time I thought, if that's who I am, then I'll be. I think it's actually worth it.
Shortly before, Benny Andersson had led a singalong with ABBA's old hit "Mamma Mia", with the chorus replaced by "Magdalena".
I'm a little unsure why I'm here, Benny Andersson says to the audience, but I think it's because I played for Olof Palme, and I've played for Anna Lindh.
So I thought I could play for Magdalena too, he says to the cheers of the audience.
Ahead of the final sprint, party leader Magdalena Andersson says that "a new direction" for Sweden is within reach.
"It's fantastic to have Benny Andersson here and cheer up the party workers," she tells TT afterwards.
