A giant boombox-shaped toilet, co-designed by Sir Rod Stewart, has been unveiled at Glastonbury Festival. The Boombox Bog houses a toilet behind the tape deck of a giant blue boombox decorated with leopard print, a pattern often worn by Sir Rod. The veteran rockstar, 80, will perform at the festival and has teamed up with WaterAid to highlight the importance of clean water and decent toilets. Festival-goers can listen to Sir Rod's hits from the Boombox Bog while also hearing water-themed messages from the singer. WaterAid, a charity partner of Glastonbury since 1994, supports water and sanitation services on site and globally.
