oh whats the name of that song?

I really wanna know the name of this song....The only lyrics I can remember is pretty much from the chorus and goes a bit like this:

SO COME ON LETS DANCE, LETS DANCE, LETS DANCE, LETS DANCE TONIGHHHHHHHHHHHTTTTTTTTTTTTTTTTTTTTTTTTTT


And is in a upbeat rythme as I found one a second ago on youtube but was really slow .... hope you can help me people

PEACE

Maybe you mean Donna Summer's -Last Dance ?
Here is an uptempo remix , the original is a bit slower , but not much..

It's actually the same song, just a different remix - the Rockamerica remix.
