For want of a nail the shoe was lost.
For want of a shoe the horse was lost.
For want of a horse the rider was lost.
For want of a rider the message was lost.
For want of a message the battle was lost.
For want of a battle the kingdom was lost.
And all for the want of a horseshoe nail.
派生を改変して「やぎさんゆうびん」の歌詞に合わせてみる。
くぎーがないからていてつ尽きた♪
ていてつないからお馬が尽きた♪
おーうまがないのできーしがまーけた♪
きーしがないのでおくにがきえた♪
