The 'White Light' hitmaker says he was ''so in awe'' of the 'Rehab' singer's ability and is devastated that he never got around to collaborating with Amy before her tragic death from accidental alcohol poisoning in July 2011.
He said: ''There is one [song] I wrote, I was hoping to sing with Amy Winehouse. I was so in awe of her talent, bless her heart I never got to offer it as a duet.''
George was in a coma for three weeks after falling ill with pneumonia last November, and when the 'Careless Whisper' singer initially woke up he couldn't stop laughing at his own jokes and found that his accent had bizarrely changed to echo the voice of a person from Bristol, South West England.
Speaking on Magic 105.4, the 49-year-old star - who was born in London - added: ''Apparently I woke up and was doing stand-up comedy for two whole days and laughing so hard at my own jokes.
''When they first woke me up and they ask 'George, George, do you know who you are?' and all I said was 'King of the world!' I was joking obviously but I cannot believe I woke up from my near death experience making jokes.
''I kept speaking in that accent but while my sisters were all hugely relieved that I had come out of this situation, while they were laughing, the doctors were quite worried that I had some form of brain damage.''
George was treated in Vienna, Austria where he fell ill and wants to repay the doctors who treated him for saving his life.
He said: ''On the first night of my 'Symphonica' tour, the doctors that saved me will be in The Front row.''
