Jack Saunders and Jo Whiley get ready for the first headliner of the weekend, the 1975. There is plenty to see before then with the return of Scottish rockers Biffy Clyro to the Pyramid Stage. New York rapper Busta Rhymes takes over the Other Stage on his first visit to Worthy Farm, while Rotherham singer-songwriter and musical theatre star Self Esteem brings songs from her recent album A Complicated Woman to the Park Stage.
