Genie - thank you so much for this" I learned the Norwegian National Anthem (and another song, Per Spelman) by ear something like 56 years ago when on a Devonia school cruise to Iceland and Norway!!! Have been able to sing it ever since - without actually knowing what I was singing about! I could follow the language well enough to note I'd either misremembered a phrase, or possibly been taught it incorrectly?
_ This was the year A Hard Day's Night came out, and a boatload of teenagers (the ones who were not seasick!) screamed their heads off every evening in the cinema - we were supposed to only attend only one viewing, but we all crammed in to watch the newly released film!
