I discovered the opening chord to this song just playing around and figured out the rest
help from IRONCOOKARU who made the other tab to this song. Props goes to him for
the basis for the chord progression, I'm just putting it the right chords for what Colin 
plays.

Verse:

Em
I Am A chimbley

A chimbley sweep

No shoes to hold my feet

On the rooftop

In dead of night

You hear me cry

Your day will come in peace
