Swift is set to perform five nights at Wembley Stadium in the UK capital in her first appearance on stage since a terror threat led to her Vienna shows getting cancelled. UK correspondent Enda Brady says fans without tickets have been asked not to gather outside the venue to listen to the gig. LISTEN ABOVESee omnystudio.com/listener for privacy information.
