I want to know the answer to the following question:
What type of festival is Glastonbury famous for
All the background I'm provided with is that "The town of Glastonbury has mythical associations, including legends of a visit by the young Jesus of Nazareth and Joseph of Arimathea, with links to the Holy Grail, King Arthur, and Camelot, identified by some as Cadbury Castle, an Iron Age hill fort.". Is that enough to answer the question?
