Found at My Bluegrass Song Book:

WILLIE ROY, THE CRIPPLED BOY

His age was seven years today.
He don't know what it is to play.
Each night before he goes to bed,
This little prayer he always says:

(Cho.:) Now I lay me down to rest.
Dear God, please give me happiness.
I'm praying so my dreams come true,
So I can walk and play with you.

His name they call him Willy Roy.
He's just a little crippled boy.
But now the tears roll down his cheeks.
I wipe them off so he can sleep. (Cho.)

Someday I hope you can go out
And play with me and walk about
I won't scold if you should cry
So soon, be good, my son, good night. (Cho.)
