This is a very loose interpretation, and it will definitely not sound like the original accompaniment,
but hopefully it sounds nice anyway! Have fun :)

[Verse 1]
Amaj7     F#m     G#maj7       C#m
Summertime, and the livin' is easy
(C#m)    F#m                      G#maj7               
Fish are jumpin' and the cotton is high
       Amaj7        F#m       G#maj7       C#m
Oh, your daddy's rich and your ma is good-lookin'
   E           F#m    G#maj7   C#m
So hush little baby, Don't you cry


[Verse 2]
Amaj7                F#m           G#maj7   C#m
One of these mornings you're gonna rise up singing
           F#m               G#maj7
And you'll spread your wings and you'll take to the sky
     Amaj7             F#m     G#maj7          C#m
But 'til that morning, there ain't nothin' can harm you
     E         F#m   G#maj7   C#m
With Daddy and Mammy standin' by
