George Michael writes song about illness

London - George Michael is writing a song about his near-death battle with illness in a Vienna hospital last year, the British singer announced on Twitter on Wednesday.

Michael, 48, was diagnosed with severe pneumonia in November and treated in the Austrian capital where he was taken ill.

He was forced to postpone his tour and spent several weeks in hospital, describing his illness as "touch and go".

'A busy boy'

On his Twitter feed, he wrote: "I've been a busy boy in the studio this week...finally ready to write about what happened to me in Vienna...and how grateful I am to be given another chance to live and breathe alongside you all in this wonderful world that we share."

He added that he wanted to repay the "unending kindness" his fans had shown him with new music, and said he had begun to write the track which will be called White Light.

The Careless Whisper star announced last month that he was back in good health and would re-start his postponed Symphonica tour in September.
