Heres another great version of katy perrys chained to the rythm with a mashup of i feel it coming by mike tompkins. I enjoy trawling through youtube for unheard music and little known versions of songs so follow if you want to see what i discover please follow....
What i love about this version is he goes through every instrument he makes with his mouth from piano to drums untill they are all playing together.
Again all credit to mike tompkins!
