Here's some behind-the-scenes footage of Beyoncé doing the Ego dance routine with Robyn's "Dance Hall Queen" overlayed on the video. Quite fitting, wouldn't you say? :]

EDIT: According to thoorn, this was used in the I Am... Tour DVD as an intro to Ego.

This video use in I am world tour DVD for intro Ego

I thought Beyonce sang a cover

RIGHT???!? I WAS ABOUT TO DIE.

Someone's getting warned for this ****ery.

Can't lie, I was interested to see how Beyonce would do on her song. I imagined a strange strange sonic mess personally.

So I'm rather happy she hasn't tackled Robyn. Yet.

I thought she was singing it.

So disappointed

The song does not fit with the video....
