If you’re reading this, Kate Bush or Prince – because obviously that’s likely – turn your eyes away now. Rather than encouraging fans to put their smartphones away at gigs, it looks like The Vamps want to get the devices proudly held aloft. At least, that’s our reading of a new iPhone app that we spotted go live this weekend called #FlashTheVamps. Released as a free download on the App Store, it’s described as a “new live event feature app” to be used at gigs. “Bring your phone along to an event, and when the boys shout out, start your app and hold up your phone to become part of the show!” explains its App Store listing. What actually happens is left mysterious for now, although we’ll take a wild punt and suggest flashing lights are involved. Fans will also be able to use the app to check upcoming tour dates and buy tickets.
