Sir Billy went on to explain his decision to quit his comedy career.
He revealed while addressing his health struggles: “Since the Parkinson’s I’m still the same in many ways, but I don’t think as sharply as I need to to be a stand-up.
“I’ve done 50 years and that’s plenty. Quitting is the right thing to do.
“I don’t miss it. I won’t miss the panic before going on. It’s terrifying, like walking the plank.
“My nerves got worse as the years went by. I used to meditate for 20 minutes to calm myself down – except sometimes I’d turn up too late to meditate and would just have to rush straight on.”
