This is how I've been performing this song in my solo act for years. Maybe it will work 
you too. www.JenningsMusic.net

Under the Boardwalk


Intro:       C

             C                                          G
Oh, when the sun beats down and melts the tar up on the roof,
                                       G7                     C    C7
and your shoes get so hot, you wish your tired feet were fire proof

          F                     C     Am
Under the boardwalk, down by the sea, yeah,
      C                   G                  C
on a blanket with my baby, that's where I'll be


And from the park you can hear, the happy sounds of a carousel
You can almost taste the hotdogs and french fries they sell

Under the boardwalk, down by the sea, yeah,
on a blanket with my baby, that's where I'll be

          Am
Under the boardwalk, out of the sun
          G
Under the boardwalk, we'll be having some fun
          Am
Under the boardwalk, people walking above
          G
Under the boardwalk, we'll be making love
          Am
Under the boardwalk, boardwalk

(Repeat first verse and chorus to end)
