One Direction delighted 47 sick children at a screening of their movie on Sunday (15.12.13) by bursting in to perform a selection of their hits and answer questions from fans.
Four members of the group - Harry Styles, Louis Tomlinson, Liam Payne and Niall Horan - surprised youngsters at a screening of their movie 'This Is Us' by bursting into the Cineworld in Wembley, north London, shining torches before treating the audience to a selection of acoustic versions of their hits.
The guys then took part in a Q&A session with their fans.
Harry joked: "You can ask anything you like - passwords, credit cards, phone numbers."
At one point, one little boy was allowed to join the band on stage and take the empty seat of Zayn Malik - who could not attend because he was ill - after confessing he dreamed of going on tour with the band.
Fan Eleanor Gabriel, 12, of Ramsgate, Kent, South East England, who has muscular dystrophy, was one of those in the audience.
She said: "It was my best day ever."
The 47 children were all given a signed One Direction shirt, a watch, and two tickets to the group's 2014 tour.
Speaking after the visit - which was organised by charity Rays of Sunshine - Harry said: "Their attitudes are incredible, you learn so much from them."
