I'd do this for you.

I’d fight the biggest man alive
I’d wrestle wolves and bears
I’d even go to church each day
I’d say the longest prayers
I’d give up all my vices
I’d right all of my wrongs
I’d put my pen to paper
I’d write the sweetest songs
I’d work for every charity
I’d give up all my worth
I’d help to save the planet
I’d dig the hardest earth
I’d meet up with the devil
I’d sell my heart and soul
I’d throw away my vinyl
I’d stand on burning coal
I’d walk into the ocean
I’d swim against the tide
I’d run until my lungs burst
I’d laugh until I cried
I’d do all these things gladly
Just to see you smile again
I'd do them every day I breathe
Just to take away your pain.
