Line up alternate facing chairs, one less than the number of guests playing the game.  While the music is playing all of the guests walk around the long line of chairs.  Once the music stops everyone needs to sit down on a free chair.  The person left standing is out of the game.  Take away a chair each time someone is out.  Keep going until you are left with two guests and one chair.  In the last round the person to sit on the chair first is the winner
