I am looking for the history/author of this song. The opening stanza is:

I have roamed in foreign lands and far off Australia's strands
My mind turns to Erin when my days work is done
I've roamed England o'er and o'er and now I'm in Columbia's shore
The birthplace of freedom and famed Washington.

Would be nice to know something about the song considering it is the 1000th anniversary of the Battle of Clontarf tomorrow.

I would appreciate any assistance in this regard
Thanks
