What is the song sung by the three sisters that has fireflies in the lyrics

Three Sisters sing songs with fireflies in the lyrics is "fireflies" this collection of songs. Lyrics for the fireflies fireflies slowly fly, summer night in the summer night wind blowing gently, afraid of the dark children sleep at ease, let the fireflies give you a little light, burning a small figure in the night, for the night travelers light up the direction of the road, the short-lived life efforts to shine, so that the darkness of the world is full of hope, fireflies fireflies fly slowly, my heart my heart is still in the chase.
