Comic Billy Connolly said he "could have done more" to help tragic actor Robin Williams, who was found hanged last month.
The Scottish stand-up favourite, known as the Big Yin, said Williams was "a joy to be around".
Father-of three Williams, 63, was found unconscious by his personal assistant in August at his home in San Francisco. Initial reports suggested the Mrs Doubtfire actor killed himself.

But Connolly, who like Williams has battled Parkinson's disease, told the Mail on Sunday's Event magazine: "In my quieter moments I do sometimes think I could have done more (to help him).
"It's a lonely life, showbusiness. You spend a lot of time on your own, and if you dwell on these things you can hurt yourself, as Robin proved."
