Yes; as a child,I found it hard to understand "There is a green hill far away,without a city wall" when we were required ( alright then,forced) to sing that hymn. And none of the teachers ever explained it, either !! At least "Folk Music",or something quite close to it,was in the curriculum in those (1950s) days,as was Orchestral music & country dancing !! What primary schools are like that today,I wonder ??
