The song One World is set to feature on their forthcoming new album Moon Music which the band say they “have nearly finished." The band posted on IG simple instructions of how you can get involved: "All you have to do is record yourself singing 'Ahhhhh' for a few seconds at oneworld.coldplay.com (link in bio). You can either copy the note on the site, or sing a G or C in any octave. Thankyou so much." On investigation the site is pretty cool, so if you fancy a fun activity on your Friday... why not. That said, we'd love to know who is doing the PPL registrations for this... Sing here
