Ninety-Nine Bottles of Beer On The Wall
(source: "The Worm Song and Other Tasty Tunes, Janet Wilson, 1993.)

Ninety-nine bottles of beer on the wall,
Ninety-nine bottles of beer,
If one of those bottles should happen to fall,
Ninety-eight bottles of beer on the wall!

Ninety-eight bottles of beer on the wall,
Ninety-eight bottles of beer,
If one of those bottles should happen to fall,
Ninety-seven bottles of beer on the wall!

Continue counting backwards all the way to one bottle of beer:

One bottle of beer on the wall,
One lonely bottle of beer,
If that lonely bottle should happen to fall,
No more bottles of beer on the wall!

Alternate version:

Ninety-nine bottles of beer on the wall,
Ninety-nine bottles of beer,
Take one down, pass it around,
Ninety-eight bottles of beer on the wall!
