I took my inlaws to A medieval Banqueti at Ruthin Castle in Wales a couple years ago, and although the entertainment was obviously created for the tourists, the local chorus and one fine actor did a rendition of Eli Jenkins'Prayer from Under Milkwood, and as the fellow recited this wonderful work by Dylan Thomas, the Chorus was humming "All through the Night" (I believe it is A Welsh hymn,) quietly behind the reading.....Quite magical
