Being in serious need of displacement activity and seizing the opportunity for a gratuituous time-wasting google to discover whether he's dead, the only reference I found would seem to be on Wikipedia, which alleges (or did ten minutes ago) that he died at around 1500GMT from massive haemorraging, having been admitted to hospital with a kidney problem. Someone seems to have taken the opportunity to edit the wiki piece and write 'Lies!' underneath the suggestion.
You'd have thought that some British media outlet would be reporting this as breaking news by now if the death occurred more than ten minutes ago, but as yet, nothing appears to have materialised.
Of course, it could be a misunderstanding of him dying on stage in Jamaica thanks to an ill-advised 'Chalky' sketch...
Whilst I can't say I thought he was very funny and I found a lot of his remarks distasteful he did do a lot of work getting entertainers out to entertain the troops. So I think calling him a c@nt is a bit harsh.
Davidson died in a Jamaican hospital this afternoon aged 55. He was admitted to the Richard Baldwin Hospital, Kingston, in the early hours of this morning (21st Feb) with a kidney complaint, and was later found hanging in a treatment room in the hospital. An initial presumption of foul play was ruled out, and a verdict of suicide appears more likely.
