There is certainly something about children singing, and I can remember quite a lot of the songs/tunes mentioned "within the woodland flowery gladed, by the oak trees mossy moot" conjured up a lovely picture (hope I have the words right). When I worked at a school, I shared an office with the welfare officer, and if it was a summer's afternoon, the windows would be open and the sound of children singing would make us both sigh. Lovely. Pity schools no longer seem to have the assembly with hymns first thing in the morning.
