(ed: also sung to the tune of 'Yesterday' by the Beatles)

Version 1:

Leprosy,
I'm not half the man I used to be,
Since I became an amputee.
Oh, I believe in leprosy!

Version 2:

Leprosy.
All my skin is falling off of me.
I'm not half the man I used to be,
Since i contracted leprosy.
Kiss me quick, before the skin falls off my upper lip.
