I play that one in Dropped-D (I believe John Doyle does as well). I got the chords off the Solas version and what I came up with goes like this:
Intro

D/ C/ G/ C/ D/ C/ G/ Am/ C/ D/ C/ D/ C/ G

G       D          C       G
In Newry town I was bred and born,
             D         C       G   
In Stephen's Green now I lie in scorn.
            Am          C       D
I served my time in the saddling trade,
         G       C      D
I always was the rovin' blade,
         G       C      G
I always was the rovin' blade.

Instrumental Bridge:

Em/ Bm/ C/ D/ C/ D
Em/ Bm/ C/ D/ C/ D/ C/ G

That's the way I hear it, good luck.

Oh, also a 2nd position G chord without the 3rd (lift up your middle finger to eliminate the B and sound the G at the third string) works well throughout and Solas used the bridge as an intro in some versions, as I recall. vl
