I know there is only a slight similarity with the song you posted above, but perhaps it's a start. I got this from http://www.sd.monash.edu.au/~exon/words

WHERE THE RIVER SHANNON FLOWS
Words and music by James I. Russell, ©1905.

            C
  There's a pretty spot in Ireland
    F                 C
  I always claim for my land
             a                e           D            G
  Where the fairies and the blarney will never, never die
            C                   C7
  It's the land of the shillelagh
      F                     C
  My heart goes back there daily
          F             C               G7                  C
  To the girl I left behind me when we kissed and said goodbye
                   F                   C
  CHORUS:   Where dear old Shannon's flowing
                         F                      C
            Where the three-leafed shamrock's grows
                      a            e            D            G
            Where my heart is I am going to my little Irish rose
                     C                    C7
            And the moment that I meet her
                    F                  C
            With a hug and kiss I'll greet her
                         F              C                G7             C
            For there's not a colleen sweeter where the River Shannon flows.

Sure no letter I'll be mailing
For soon will I be sailing
And I'll bless the ship that takes me to my dear old Erin's shore
There I'll settle down forever
I'll leave the old sod never
And I'll whisper to my sweetheart "Come and take my name, Asthore."

Recorded by Bing Crosby et al.

Hope this helps,
