A singer in Britain's Got Talent's B-Positive Choir has revealed the tragic loss that prompted her to perform.
As the name suggests, B-Positive is a choir with a message: it was put together by the NHS Blood and Transplant unit to encourage the public to give blood.
All of the members either suffer from, or know someone who suffers from sickle cell disease.
In their audition, their "soulful, honest, authentic" performance of Andra Day's 'Rise Up' triggered tears from Amanda, who explained: "I found the whole thing really moving because blood donors saved my life."
Speaking ahead of the live shows, Simonne Kerr opened up about the personal loss that caused her to join the choir.
She opened up to the Daily Mirror about how her son Kavele sadly passed away from complications of sickle cell disease in 2015.
Speaking to the newspaper, Simonne said: "When I'm with the choir, I look either side of me and see new friends who have been affected by the same disease which took Kavele.
"They know the physical and emotional pain of it. We support each other and there's a real family vibe. When we sing, we don't just rattle through a song. We sing with real feeling that comes from the bottom of our souls."
She added: "Singing can be such an uplifting experience so joining the B Positive choir seemed the obvious way to raise awareness of the urgent need for more young and black people to give blood while doing something positive and motivational."

B-Positive Choir have been chosen as this year's wild card act for the final.
The Live Final airs on ITV on Sunday June 3 at 7.30pm
