I was going to stick a link to Sydney Carter's John Ball on the DT - but it's not there because of hassles with the publishers (not Sydney Carter's fault).
But there's always another way - and here is a link to a post I did some time back with the words of the song. Which I last sang in what I think is the oldest Friends' Meeting House in the world, in Hertford in Hertfordshire), where they had a folk evening. P>
One of the things Friends are best at is dealing with ructions in any kind of meeting by calling for a few moments of silence. In a way we've got that built into the Mudcat communication structure. It's one of the things that helps stop us going too far over the edge at times.
Andy another thing I like about them is the way it seems to be quite possible to be a Buddhist or a Catholic or a Jew and still be a Quaker.
