Singer-songwriter John Grant had just finished playing at St George's church in Kemp Town on Thursday when the computer was taken from the stage. He wrote on Facebook: "I am shocked and just completely speechless." One band member, drummer Kristinn Agnarsson, tweeted that one of the crew had "looked away for a bit, and then it was gone." Sussex Police said the theft had been reported just after midnight and the laptop had not been returned or found. Mr Grant said: "After our show in Brighton tonight, someone who was apparently in the audience stole my computer off the stage, which has my entire life on it. I have so many things on that computer which I need.
