An Irish group called "The Barleycorn" had a hit with this song, and it was also recorded in America by Richie O'Shea on a Rego album called "We'll Take You Back to Ireland" (Rego's # 516 328 7800). Here's the lyrics:

SING, IRISHMEN, SING

Sing Irishmen sing
so the sounds of your voices will ring
and let the world know that it really is so
sing irishmen sing.

I dream of a beautiful picture,
no more need we think of the past,
there's singing and dancing in Ireland,
and the people are happy at last.
The sound of the gunfire has ended
the rifles will bring no more pain
theres singing and dancing in Ireland and the people are happy again.

(chorus)

I know that it's only a dream now,
but my hopes will always remain,
to see the sunshine over Ireland,
when the people are happy again.

(repeat chorus)
