 Ellen Hurtum. Now, Glastonbury opened its gates to festival goers this morning. It began on Worthy Farm, a working dairy farm, all the way back in 1970. And it's grown and grown ever since then to become the biggest event of its kind in the world. As well as the headline acts this year, such as Dua Lipa, Coldplay and Scissor, there's also the Legends set on Sunday, which has given over to a seasoned star and often someone who's never played Glastonbury.
