Sir Michael Parkinson and Sir Billy Connolly have been friends for decades.
The veteran TV presenter has hosted the comedian on his talk show several times over the span of their friendship.
But when they recently saw each other, Connolly didn’t recognise his old friend.
“The sadness of Billy now is that wonderful brain is dulled,” Parkinson said on British lifestyle show Saturday Morning with James Martin.
“I saw him recently, he’s now living in America, and it was very sad because I was presenting him with a prize at an award ceremony.”
Parkinson said their encounter was a bit stunted, because he wasn’t sure whether Connolly recognised him.
“We had an awkward dinner together because I wasn’t quite sure if he knew who I was or not.
“But we were walking out after the presentation to go down and have our picture taken and he turned to me and put his hands on my shoulders.
“He said to me, ‘How long have we known each other?'”.
The 83-year-old said that was a tough moment.
“To know someone as long as I knew and loved Billy, it was an awful thing to contemplate, that that had been taken from him.”
