The other tabs seem off to me; this seems to sound right.

CAPO 1
I find it easier to just use a capo on the first fret. That way you can use normal open 
rather than sharps and flats.

  G                   Bm
A hungry feeling Came o'er me stealing
        C                         Am
And the mice were squealing In my prison cell
     G                   Bm
To begin the morning The warden bawling
     C                       Am
"Get up out of bed, boy! And Clean up your cell!"

        G                   Bm
And that auld triangle went jingle-jangle
     C                     Bm      G
All along the banks of the Royal Canal
(finish bar with G which leads into next verse)

On a fine Spring evening
The loike lay dreaming
And the sea-gulls squeeling
High above the wall
Oh! the day was dying
And the wind was sighing
As I lay there crying
In my prison cell

And that auld triangle went jingle-jangle
All along the banks of the Royal Canal

Oh! the screw was peeping
And the loike was sleeping
As he lay there weeping
For his poor gal

And that auld triangle went jingle-jangle
All along the banks of the Royal Canal

In the female prison
There are seventy women
And I wish to god it was with them
That I did dwell

And the auld triangle went jingle-jangle
All along the banks of the Royal Canal
And the auld triangle went jingle-jangle
All along the banks of the Royal Canal
