Greg James and Gemma Cairney kick off BBC Three's live coverage from the world's greatest music festival. Highlights from performances on the first afternoon on the Pyramid stage include 19-year-old Nottingham singer-songwriter Jake Bugg and West London chart dynamite and general girl-about-town Rita Ora making her Glastonbury debut. Greg and Gemma chat with some of the other artists performing, and out in the field live reports come from Jen Long in search of the Glastonbury magic from around the site.
