 The other day I met a \blue{bear}
 Out in the woods away out there

 \red{He} looked at me, I looked at him
 \red{He} sized me up I sized up him

 \red{He} said on me, why don't you run
 I see you ain't got any gun

 I said to him, that's good idea
 C'mon now feet, let's up and flee

 And so I run, away from there
 But right behind me was that \blue{bear}
\end{alltt}

ある日森の中 \blue{くまさん}に 出会った
花咲く森の道 \blue{くまさん}に 出会った
\blue{くまさん}の 言うことにゃ お嬢さん おにげなさい
スタコラ サッササノサ スタコラ サッササノサ

ところが \blue{くまさん}が あとから ついてくる
トコトコ トコトコと トコトコ トコトコと

お嬢さん お待ちなさい ちょっと 落とし物
白い貝がらの 小さな イヤリング

あら \blue{くまさん} ありがとう お礼に うたいましょう
ラララ ララララ ラララ ララララ
