Is this the right one? From that site:

Don't stop the music let it play one more song

The same one that's played tonight for so long

She's out with another I saw them tonight
Sitting there close together she knows that not right

So don't stop the music let it play one more song

The same one that's played tonight for so long

My pockets are empty I spent my last dime

But I've just got to hear that song one more time

[ piano ]

Don't be mad at me Mister I know that it's wrong

But I want you to hear the words of that song

So don't stop the music don't make me go home

I know she's not there and I cry all night long

So don't stop the music...
