The Mr. Brightside hitmakers were performing a show in Newcastle, England when frontman Flowers decided to head out on one of his trademark walkabouts among the audience.
He was upset when he returned to the stage and realised a chain was missing from his arm - so now he always removes his wedding ring and other valuables before shaking hands at gigs.
Flowers tells Q magazine, "I've lost a bracelet or two. I won't say in which town. I don't want to get into trouble... Ok, it was Newcastle. I don't wanna lose my wedding ring! I put them back on after the gig."
