 Krystal Weedon , one of the central characters in J.K. Rowling 's The Casual Vacancy , was very apt at doing Jay @-@ Z 's rap from " Umbrella " during their rowing competition bus trips . " Umbrella " , to the shock of the attendees , is also played at the church during the funeral service of Barry Fairbrother who used to coach the girls ' rowing team prior to his death . Similarly , the song was also played at the funeral service of another character .
