Ninety Nine Bottles of Beer

 6  6   6   -4  -4  -4  6    6  6   6
Ninety nine bottles of beer on the wall,
  -6    -6   -6  5  5   5
ninety nine bottles of beer,
-6   6  -5  -5 -5  -4    -4   -4  -5 -5  -5
If  one of the bottles should happen to fall,
  -5     -5  5  -4   -4   -4  -4  5  -5  6   6
there'll be ninety eight bottles of beer on the 
 6
wall.

This song continues counting down until you reach zero bottles of beer (If you can play that long)
