Around the World vocals on a different track?

[One More Solo]

A mate's been looking for this song, I've not heard it myself but apparently there's a track doing the rounds with the Daft Punk - Around the World vocals over a different backing, any ideas what it might be?

Is it the remix they did for the alive tour? think it's mixed in with Harder, Better, Faster, Stronger. Think it's being released as a single, plus it's on the Alive tour album.
