Just a quick comment on "Glastonbury" in an attempt to be helpful for those who may be mystified by some of the references in the lyrics (which I find pretty trite, actually). Aside from being the name of a music festival, Glastonbury per se is also a pilgrimage site/abbey with many legends and traditions surrounding it. For example, there are some Holy Grail stories, King Arthur connections, and a tradition which places St. Patrick at Glastonbury Abbey. The legend that seems the most clearly evoked in the text, however, is this one: roughly, Joseph of Arimathea supposedly came to Britain only a few years after the Crucifixion. When he made it to Glastonbury, he stuck his staff into the ground before going to sleep, and when he awoke it had blossomed and become a thorn tree ("under the flower of a miracle dream"), which still blooms at Christmas.
