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. Michael, 48, was diagnosed with severe pneumonia in November. He was forced to postpone his tour and spent several weeks in hospital, describing his illness as “touch and go”. 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’.
