The 'Yellow' hitmakers brought their 'Mylo Xyloto' Tour to the Tampa Bay Times Forum, where frontman Chris Martin played to more than 20,000 fans with photographic equipment mounted on his guitar.
The band's photographer, known as Roadie #42 on the Coldplay website, took to Twitter after the show to reveal the camera had been lost, and asked for help locating it, reported Daily Express.
"Hey Tampa folks. If you found my camera after it flew off Chris's guitar, can you shout up? Thx (thanks)!," he posted.
Within a few hours, a pair of honest concert-goers handed in the gadget, and a spokesperson for Coldplay tweeted, "Just to confirm: ?#42cam? has been found! Thanks so much to Julia and Brianna!."
