Or this one...

He'll call you very bright and early
wake up all the neighborhood.....
He'll sing to every boy and girlie
his little serenade on wood

You can hear him picking out a melody
peck, peck, pecking at the same old tree
He's just as happy as a bumble bee
all day long

Come on and try his rhythm
and let your heart beat with him
and you will hear that
dig a dig dig, dig a dig dig
happly little woodpecker song


There may be some more verses but that's all that I know
Bert.
