To make one thing absolutely clear: this is not Friday's song of the day. Which is not to devalue it ... but ... well, y'know.
It's Dawn French, spoofing Bjork.
As Bronagh commented, there is a certain eery resemblance between Ida Maria, as featured in Wednesday's post, and Dawn French. Which only serves to further the uneasy impression that the whole of Ida Maria's video might be some kind of tongue-in-cheek wind-up.
I don't think it's meant to be.
But compare the videos. Don't you see the resemblance?
