Puff, the magic dragon lived by the sea

And frolicked in the autumn mist in a land called Honah Lee

Little Jackie Paper loved that rascal Puff

And brought him strings, and sealing wax, and other fancy stuff

}
\ChorusBlock{

Oh, Puff, the magic dragon lived by the sea

And frolicked in the autumn mist, in a land called Honah Lee

Puff, the magic dragon, lived by the sea

And frolicked in the autumn mist, in a land called Honah Lee

}

\VerseBlock{$\beta$}{

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 whenever they came

Pirate ships would lower their flags when Puff roared out his name

}

\ChorusBlock{

Oh, Puff, the magic dragon lived by the sea

And frolicked in the autumn mist, in a land called Honah Lee

Puff, the magic dragon, lived by the sea

And frolicked in the autumn mist, in a land called Honah Lee

}


\VerseBlock{$\gamma$}{

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

}

\ChorusBlock{

Oh, Puff, the magic dragon lived by the sea

And frolicked in the autumn mist, in a land called Honah Lee

Puff, the magic dragon, lived by the sea

And frolicked in the autumn mist, in a land called Honah Lee
