Dad always sang it like dis:

Hush, little baby, don't say a word.
Papa's gonna buy you a hummingbird.
If that hummingbird should fly,
Papa's gonna show you the evening sky.
As the nighttime shadows fall,
Papa's gonna show you the crickets' call.
As their song drifts from afar,
Papa's gonna show you a shooting star.
As that star fades from view,
Papa's gonna read a book to you.
When that story has been read,
Papa's gonna buy you a warm bedspread.
When that quilt begins to wear,
Papa's gonna buy you a teddy bear.
When that teddy bear's been hugged,
Papa's gonna hunt you a lightnin' bug.
And if that lightnin' bug won't glow,
Papa's gonna play on his old banjo.
And if that banjo's outta tune,
Papa's gonna show you the harvest moon.
As the moon drifts from the skyyyyyyyyyyyy.................
Papa's gonna sing you a lullaby.
