(Alternatively, I find C G7 C G7 works nicely as a beach bum lazy intro)
I used to play this with G7 where the Gaug is till the suggestion below. G7 works okay if Gaug is too tricky.


[Intro]
C C#dim Dm  Gaug/D#

[Verse 1]
      C             Gaug         C                 Gaug
I'm a poor Hawaiian beach boy, a long way from the beach
       C                  C/G             C  C7
'Cause someone shoved his face against my hand
    F             F#dim       C/G      A7    D7 G7     C   C/G
Now I'm a kissing cousin to a ripe pineapple, I'm in a can


[Verse 2]
C                    Gaug         C                Gaug
I was minding my own business but drinking daddy's juice
  C                Gaug             C    C7
I swear I'll never touch that stuff again
            F             F#dim    C          A7   D7 G7     C7
Just like a pig before he gave his all at the luau, I'm in a pen

Got those beach boy blues

Don't the time go slow

Lonely beach boy blues
     D7          D/A         G7

I want a taste of honey from my wahini's lips

I want to be her ever loving man
    F             F#dim       C/G      A7    D7 G7     C  C7
But I'm a kissing cousin to a ripe pineapple, I'm in a can
      F             F#dim       C/G      A7    D7 G7     C
