Question about a song

I was watching an episode and I heard this song and it was good but I can't find out any information on it, does anyone know what it is? I'm not sure of the first three words in the last line.

Demons come a'calling
Devils on a slope
The horseman come a'riding
And they're playing in the storm
The dark clouds keep on rolling ain't no telling where they'll blow
Well I'll follow as they lead me to the dark side of the room
Well I'll walk to the dark side of the room
