Indeed...I suspect it's been around even longer than my old bones. It was the favorite song of my old captain, Calico Yorki and so we Rumbar Pirates sang it so often it was practically engraved in my skull!

[Fond memories those were, just days spent sailing under the endlessly blue sky with ivory beneath his fingers and a tune on his lips. Simpler times before...well, before he became how he was now. The song helped remind him of those good times and of his promise to Laboon; even in the darkest of times, it had kept him going]

And what about you Luffy-san? Do you have a particular song you enjoy?
