Around 100 people will take part in a 12-hour musical marathon to raise money for Jemima’s Gift, a charity set up in memory of ten-year-old Jemima Prees.
Jemima, from Colerne, died during a family skiing holiday in Austria in February last year after she lost control on the ski slope and crashed into a tree.
Money from the musical marathon, organised by her sister Annabel, will fund activities or equipment to help children to reach their full potential.
Annabel, 16, has booked a wide variety of musical acts, including the Colerne Military Wives Choir and Mount Zion Church Choir from Hullavington.
Dad Tim Prees will play as part of the Marshfield Brass Band and Annabel plans to play the oboe or piano.
Jemima’s Gift has raised more than £50,000 so far.
Annabel said: “Jemima was an enthusiastic person and did everything she could get her hands on.
“She would have been excited about the event, she had a real love for life.
“Everyone else in my family was doing things to raise money for the charity because it was very close to their heart.
“I decided that I really wanted to do something and I thought I would use my skills in music and organising.”
Jemima, a pupil at Calder House School, played the euphonium for the Corsham Wind Association, who will also perform on the day.
The event, in Colerne Village Hall, begins at 10am on August 30 and finishes at 10pm.
Tickets are £5 and are available on the day.
