Coldplay helped a fan with a proposal during their concert at London’s Wembley Stadium on Aug. 22, but frontman Chris Martin had a few questions first. A video shows Martin joking around with the fan before honoring his request.

Martin joked that he needed to “do some basic security checks” when a fan tried to propose at his show in London.

During his concert at Craven Park on Monday, Chris Martin addressed the viral jumbotron moment between Astronomer's CEO and the company's chief people officer.
