Here's one with live band and live backing vocalists. But the band made it more rocky than discohttp://www.youtube.com/watch?v=pZaV9ouTr_k
That's a better live!
with backing voices, etc... would be fine!
^^ Just have a look at the video that balizeg posted on this page, it shows what they are aiming for concerning the dance routine.
And there are even videos floating around in youtube where u can see the whole dance rehearsal!
