The British nurse who survived Ebola has described the new Band Aid charity single as "cringeworthy".
William Pooley went back to work at an isolation unit in Sierra Leone in West Africa, despite having been airlifted to London after catching the disease.
He urged people who want to help fight Ebola to donate money to charities working with patients directly.
Pooley criticised the lyrics in the reworked version of Do They Know It's Christmas? featuring One Direction, Bono and Ed Sheeran and put together by Bob Geldof.
"On the way into work I heard the first half of it. It's definitely being talked about here among my colleagues," he told Radio Times magazine.
