A docomentry aired in America some time ago, i6 was called The Irish in America,
Long Journey Home.
I have the trans script from it but really want a copy of the actual doco.
Help !

Hi! Thanks for the question.

I found the documentary you are looking for in VHS format. It was a
difficult hunt since most stores do not have them in stock anymore.
These two websites are the only ones that have them based on my
searches.
