I think the Beatles' connection came from this: back in the 60's there was a young Welsh lassie named Mary Hopkin (no "s") who had a hit with this song. She had been the winner on a talent show called Opportunity Knocks, and had been immediately snapped up by the Beatles management, who handled her career, with personal assists and arrangements from Paul McC. himself. She also had a big hit with Those Were The Days. All the best. Seamus
