Peter, Paul and Maryの「Puff the Magic Dragon」という曲です。

Lyrics：

Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali
Little Jackie Paper loved that rascal Puff
And brought him strings and sealing wax and other fancy stuff
Oh, Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali

Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali
Together they would travel on a boat with billowed sail
Jackie kept a lookout perched on Puff’s gigantic tail
Noble kings and princes would bow whene’er they came
Pirate ships would lower their flags when Puff roared out his name
Oh, Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali

Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali
A dragon lives forever, but not so little boys
Painted wings and giant’s rings make way for other toys
One gray night it happened, Jackie Paper came no more
And Puff, that mighty dragon, he ceased his fearless roar
His head was bent in sorrow, green scales fell like rain

Puff no longer went to play along the cherry lane
Without his lifelong friend, Puff could not be brave
So Puff, that mighty dragon, sadly slipped into his cave

Oh, Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali
Puff the magic dragon lived by the sea
And frolicked in the autumn mist in a land called Honali
