Text of the english adaptation of the japanese children's song "Hotaru koi".
"Come firefly", by David Larson.

Ho, firefly, come, there's some water that's bitter to taste,
come, here's some water that's sweet to your taste;
ho, firefly, ho, up this mountain path.

Firefly's daddy struck it rich, so he's got lots of dough,
no wonder that his rear end sparkles in the dark.
Ho, firefly, up this mountain path.

In the daytime hiding 'mongst the dewy blades of grass,
but when it's night, his lanter burns bright.
E'en though we've flown all the way from India, zoom!
and those sparrows swarm to swallow us.

Ho, firefly, come, there's some water that's bitter to taste,
come, here's some water that's sweet to the taste;
Ho, firefly, up this mountain path,
look! see a thousand lanterns sparkling in the dark, ho, up this mountain path.
