Summertime is an aria composed by George Gershwin for the 1935 opera Porgy and Bess. The lyrics are by DuBose and Dorothy Heyward, and Ira Gershwin. The song soon became a popular jazz standard.

And the livin' is easy,
Fish are jumpin'
And the cotton is high.
Your daddy's rich
And your mamma's good lookin'
So hush little baby
Don't you cry
One of these mornings
You're going to rise up singing,
Then you'll spread your wings
And you'll take to the sky.

But till that morning
There's a'nothing can harm you,
With daddy and mamma standing by.
