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.

Coldplay frontman Chris Martin’s ‘kisscam’ sent pulses racing in Wembley last night as he captured a marriage proposal between two fans - as crowds roared in the stadium. Martin’s kisscam is a light-hearted interval in the middle of Coldplay concerts, which captures impromptu moments of fans enjoying themselves.

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