The bugle call "Taps"
"Taps" is actually just a bugle call, not a song with lyrics. Many bugle calls had words associated with them as a mnemonic device to keep a rhythm, but are not lyrics. Horace Lorenzo Trim is often credited for the "lyrics" intended to accompany this music, which is why Taps is sometimes called "Day is Done."
Day is done, gone the sun,
From the lake, from the hills, from the sky;
All is well, safely rest, God is nigh.
Fading light, dims the sight,
And a star gems the sky, gleaming bright.
From afar, drawing nigh, falls the night.
Thanks and praise, for our days,
'Neath the sun, 'neath the stars, neath the sky;
As we go, this we know, God is nigh.
Sun has set, shadows come,
Time has fled, Scouts must go to their beds
Always true to the promise that they made.
While the light fades from sight,
And the stars gleaming rays softly send,
To thy hands we our souls, Lord, commend.
