The singer hopes to raise awareness of the vital research into the disease to be carried out at Newcastle University.
His plea was broadcast on Sunday on BBC1 and today on BBC2. Richard is the patron of the Alzheimer's Research Trust. He also lost his mother to the disease last year. In his words he and his sisters were robbed of the vibrant woman they once knew and it was unbearable for them not being able to do anything about it.
Sir Cliff Richard has represented the United Kingdom twice at the Eurovision Song Contest - in 1968 with Congratulations and 5 years later with Power To All Our Friends. He has sold over 250 million albums worldwide and is one of the most recognized people in the UK music scene.
