The family of late Barnstaple teenager and organ donor campaigner Katie Gammon is organising a special celebration for what would have been her 18th birthday.Katie would have turned 18 on August 21, the date of The Breathe Festival, a day of live music and entertainment at Barnstaple Pannier Market. The day will feature performances from Taylor Swift, Robbie Williams and Olly Murs tribute acts, as well as local acts The Stolen Page and Nikita Payne. As well as live music, the festival will have food, drink and a childrens area with a bouncy castle, fun shows and face painting. Proceeds from the event will go to local charities Little Bridge House, the Caroline Thorpe Ward and Everything Ellie. Katies dad, Andy Gammon, has been organising the festival along with other members of Katies family. He said: As its her birthday weekend, we thought wed have one big bash, which she would have enjoyed, and we want to make it a big party. Weve got bands that Katie would have like to have seen and the non-tribute acts are all ones that she would have liked. Were really pleased with how everything is going, and there are lots of local companies that have helped us out and sponsored us, which we are very grateful for. Organisers hope to raise £20,000 for the three charities, but also raise awareness of cystic fibrosis and encourage people to sign up for organ donation. Katie underwent a double lung transplant in August 2013, died in August last year just days after her 17th birthday. She fought a lengthy battle with cystic fibrosis but had spent the last couple of months of her life in hospital suffering with lung rejection. Tickets for the festival are £15 for adults and £8 for children, with childrens tickets giving free access to all activities at the festival.
