Black Handkerchief of Happiness

Black Handkerchief of Happiness is a song that Brook sung to awaken his crew when he was alive. It is loud, fast paced and annoying.

Recently a CD version was released in Japan with the full song which only lasts 30 seconds 

Lyrics
Oh White Handkerchief

Don't let him find you!

Run away

Oh white handkerchief

Don't let the octopus get you!

Watch out for the ink!

Look, there's a squid as well!

That's the ink again!

Oh White Handkerchief

It's the all inked Black Handkerchief of Happiness

Kanji
白いハンカチ

見つかるなヤツに

にげろ

白いハンカチ

つかまるなタコに

それスミだ イカも来たぞ

またスミだ

白いハンカチ

スミだらけ幸せの黒いハンカチ

Romanized Lyrics
Ika mo kita zo Mata sumi da Shiroi hankachi Sumi darake shiawase no kuroi hankachi

Trivia
The title of the song is a parody of the japanese film "The Yellow Handkerchief" (幸福の黄色いハンカチ, Shiawase no kiiroi hankachi-The Yellow Handkerchief of Happiness).
