He was adopted by Lynn Cawley - a campaigning Methodist Minister whose devotion to Josh ensured that he lived his short life as positively and 'normally' as possible.
Lynn couldn't just be his loving mum though - she was expected to be his palliative care consultant, his nurse, his campaigner for compensation and she had to fight the ongoing battles with the system.
The play explores their real story - having to accept that Josh's needs were too 'complex' for the hospice - dealing with Josh's transition from boy, to teenager to adult and all the time being his interpreter.
The play is performed by professional actor Joey Taylor who gives the voice to Josh - the voice that Josh never had.
