Glastonbury artists including Lianne La Havas, Gabrielle Aplin, Tim Burgess, Editors, Palma Violets, Newton Faulkner and Beverley Knight have taken part in a photoshoot for WaterAid's Pump up the Volume campaign.
The official Glastonbury charity is encouraging everyone to sign a petition asking world leaders to help ensure everyone has access to water and sanitation by 2030. The musicians were joined by Laura Whitmore and WaterAid Ambassador Rachel Stevens who've designed water-themed nail art, which is available at the festival.
