MARY HAD A LITTLE LAMB AND A SIDE OF MASHED POTATOES!!!! HAHAHA!!! 
but seriously this is very easy, and u can play around w/ distortion, 
etc.
i think sum versions of this song hav different lyrics and changes 
in the tune but this is like the "universal" version

play the notes along w/ the words
