Ann and Andy invite all celebrants to join them for refreshments in the Chapel after the service.
Anyone wishing to make a donation in memory of Tom can do so at the service or by sending a cheque to Pengelly Funeral Service (139 Fore Street, Saltash, Cornwall PL12 6AB) who are dealing with all the arrangements.
Tom's Father Andy had a renal transplant 41 years ago and much of Andy and Ann's life's research and clinical work was in trying to understand the causes of and looking after people with kidney disease.
All money raised will be split between Friends of Derriford Renal Unit and The British Kidney Patient Association (BKPA).
The thoughts and prayers of everyone at St Austell RFC are with the Demaine family at this difficult time.
