This is what I play, Capo on second fret to play along with the original 

A             D
La, La La La, La, La la la
A             D
La, La La La, La, La la la
      A                        D
She's working as a waitress in Dublin,
G                            A
Filling up the tourists with beer,
G         A            D          G
Stashing away a little cash every day,
      G          A          D
For a ticket to ride out of here,
       A                          D
Every night she feels a little bit older,
      A                     D
Every day a little wetter and colder,
G        A          D       G
No more rain for this Irish Rose,
 G                                        A
She's gonna go (She's gonna go!) where the palm trees grow.


Refrain:
            D                  A
She wants a Pina Colada in a pint glass...
            D                          A
She wants to be where the summer won't stop,
           G                    A
She wants gin clear water and milk white sand,
     G                  A
A sunburned nose and a drink in her hand
       G       A         D
With a pink umbrella on top! 


      A                        D
She's standing in line at the chipper,
G                         A
Waiting for her curry and peas,
     G         A            D         G
But dying for some of that papaya and rum,
        G         A       D
And the kiss of a coconut breeze,
       A                          D
Every night she feels a little bit older,
      A                     D
Every day a little wetter and colder,
               G     A            D         G
She's bought a thong bikini and a big straw hat
           G             A
She's gonna go and she's not coming back!


Refrain:
            D                  A
She wants a Piña Colada in a pint glass...
            D                          A
She wants to be where the summer won't stop,
           G                    A
She wants gin clear water and milk white sand,
     G                  A
A sunburned nose and a drink in her hand
       G       A         D
With a pink umbrella on top!


       A                          D
Every night she feels a little bit older,
      A                     D
Every day a little wetter and colder,
      A                         D
She's cleaning up the tables on Sunday,
          G                        A
But she's dreaming of the tropical night,
        G       A          D          G
Another five or ten in her pocket and then,
          G             A          D
She'll be closer to the price of a flight!
       A                          D
Every night she feels a little bit older,
      A                     D
Every day a little wetter and colder,
          G          A               D      G
She plays Beach Boys records and she dances alone,
    G               A
And before (before) before she goes home...
