Lyrics: Paul McCartney. Back In The World. Mother Nature's Son.

:
Born a poor young country boy, Mother natures son
All day long, I'm sittin singin songs for everyone

Sit beside a mountain stream, see her waters rise
Listen to the pretty sound of music as she flies

Du du du du ...

Find me in the field of grass, Mother natures son
Swaying dasies, sing a lazy song beneath the sun

... oh ... mother nature's son
