    Am    E                 Am
Summertime, and the living is easy, 
[ Tab from: http://www.guitaretab.com/l/louis-armstrong/301918.html ]
    Dm                          E
Fish are jumping and the cotton is high. 
 
Am                E                  Am
Your daddy is rich and your mummy is good lookin', 
 
   C                    E       Am
So hush, little baby, don't you cry. 

   Am                 E                       Am
One of these mornings you'll gonna rise up singin', 
 
   Dm                              E  
Then you'll spread your wings and you'll take the sky.

   Am                 E                    Am
But till that morning there's nothing can harm you, 

     C                      E         Am
With daddy and mammy, mammy standing by.
