[INTRO: ]
          C#          Ab  
  When the little bluebird  
          C#            Ab  
  who has never said a word  
            C#      Ab        C#       Ab  
  starts to sing   spring,  
           C#         Ab  
  When the little bluebell  
         C#            Ab  
  at the bottom of the dell  
            C#             Ab            C#         Ab  
  starts to ring—ding dong ding dong.  
           F#  
  When the little blue clerk  
         Ab  
  in the middle of his work  
           C#          Ab      F#  
  starts a tune to the moon up above,  
        C#             Ab  
  It is nature, that is all,  
         F#            Ab      C#  
  simply telling us to fall in love, 

   and that's why 


Ab 
birds do it, bees do it,  
C#              F#  
  even educated fleas do it.  
C#            Ab              F   E   Eb   D  
  Let's do it, let's fall in love. 
                C#                   Ab  
  Cold Cape Cod clams, 'gainst their wish, do it  
C#               F#  
  Even lazy jellyfish do it.  
C#            Ab              C# F# C#  
  Let's do it, let's fall in love  


                  Bb          F#  
  I've heard that lizards and frogs do it  
Ab            F  
  layin' on a rock.  
F#            
  They say that roosters do it  
Ab  
  with a doodle and cock.  


            C#             Ab  
  Some Argentines without means do it.  
C#                   F#  
  I hear even Boston beans do it.  
C#            Ab               C# F# C#  
  Let's do it, let's fall in love.

          F            C  
  Who has never said a word  
            F         C

  starts a tune, 

         Bb  
  The most refined lady bugs do it  
C                  A  
  when a gentleman calls.  
Bb  
  Moths in your rugs, they do it — 
C  
  What's the use of moth balls?  
             F           C  
  The chimpanzees in the zoos do it,  
F                       Bb  
  Some courageous kangaroos do it.

  Let's do it, let's fall in love  
               F            C  
  I'm sure sometimes on the sly you do it. 
F                    Bb  
  Maybe even you and I might do it.  
F             C                F   E   Eb   D  
  Let's do it, let's fall in love.
