The original file is:
Oh they say people come say people go
This particular diamond was extra special
And though you might be gone and the world may not know
Still I see you celestial
When I should but I can't let you go
But when I'm cold cold
When I'm cold cold
There's a light that you give me when I'm in shadow
There's a feeling within me an everglow
Like brothers in blood sisters who ride
And we swore on that night we'd be friends 'til we die
But the changing of winds and the way waters flow
Life is short as the falling of snow
And now I'm gonna miss you I know
But when I'm cold cold
In water rolled salt
I know you're with with me and the way you will show
And you're with me wherever I go
And you give me this feeling this everglow
Oh what I wouldn't give for just a moment to hold
Becasue I live for this feeling this everglow
So if you love someone you should let them know
Oh the light that you give me will everglow
The results are:
