In 1971 the show became the Glastonbury Free Festival. That’s right, free. The
event was paid for by sponsors, meaning that keen festivalgoers were treated to
acts such as the late, great David Bowie without having to pay a penny. It was
also the first year that the Pyramid Stage appeared. Designed to replicate the
Great Pyramid of Giza, the stage was one-tenth the size of the original and was
built using scaffolding and metal sheeting.
