People don't actually bother reading. To be honest, I think you'd be hard pushed to find any Scottish records with dubbed on sound effects until the 1960's. It just wasn't used on Scottish accordion instrumentals. I think Joe Meek (Telstar etc.) kind of stirred producer's imaginations, plus then tracking technology came into common currency in studios. My father recorded a 1965 single of the 'Mingulay Boat Song' with seagulls, and waves lapping in similar vein to the Alexander Brothers recording of the Dark Island from the same period. A picture in sound - it was fashionable and a novelty. But its not something that would have been used on early 78's. it just irritates when people come up with a perceived memory which is physically impossible.. to imply that recordings existed before it was ever issued under the title, as the TV series from which it gained its name was only broadcast in 1962.   A time machine would have been required!
