It's been a rollercoaster year for Sir Cliff. He lost his longtime friend Cilla Black in the summer and broke his exile from England to perform at her funeral in Liverpool.
He also continues to be investigated by South Yorkshire police over historic sex offence allegations, although top investigating officer Simon Bailey told the Sunday Times this weekend that letting the BBC film the police raid on Sir Cliff's Berkshire home was "a mistake". Cliff has always denied any wrongdoing and has not faced any charges over the allegations.
