Speaking about Parkinson’s, he said: “It takes a certain calm to deal with, and I sometimes don’t have it. I sometimes get angry with it, but that doesn’t last long, I just collapse in laughter.”

The Evening Times previously reported how Sir Billy admitted he is “near the end” and life is “slipping away” as he spoke about his life with the disease.

Sir Billy was a welder in Glasgow before becoming a globally-renowned comedian.
