Jo Whiley, Mark Radcliffe, Lauren Laverne and Phill Jupitus are this year's hosts and will be in amongst everything happening on day one of the Glastonbury Festival from Worthy Farm in Somerset. Dropping in on performances from the Fratellis on the Pyramid stage, Rufus Wainwright on the Other stage, Toumani Diabate on JazzWorld. Plus the odd acoustic performance and Glastonbury performers past and present talk about why the festival is important to them.
