Ah Plastique Paddy!
I remember watching an episode of an English TV programme about a rambling chef (or was that a rambling BBC programme about...?) ... The Fat Man goes to .... Anyway there was a segment done in Argentina ... and he visited the descendants of Irish settlers who went to Argentina in the late 19th century.
I still have, etched into a sensitive spot in my brain, the image of two dark-eyed senhorinas ... in Irish National costume ... singing a wondefully Argentinian/Spanish-accented If You're Irish, Come into the Parlour!
