For the record, here are the ORIGINAL lyrics. (Not only the tune and arrangement -- originally an operatic aria sung by a lyric soprano -- but also the lyrics have been subjected to "the folk process" (aka "the jazz process") uncountable times.)

SUMMERTIME
lyrics: Ira Gershwin, based on book by DuBose Heywood/music: George Gershwin

Summertime, an' the livin' is easy.
Fish are jumpin' an' the cotton is high.
Oh, Yo daddy's rich an' yo' ma is good lookin',
So hush, little baby, don't you cry.

One of these mornin's, you goin' to rise up singin'.
Then you'll spread yo' wings an' you'll take the sky,*
But till that mornin', there's a nothin' can harm you
With daddy & mammy standin' by.

*Note: It's not "... take TO the sky ... "
