Robin Gibb's son RJ says the Bee Gees singer's death was caused by kidney and liver failure.
Despite a two-year battle with cancer and a recent bout of pneumonia, it is believed that Gibb passed away as a result of organ failure.
Speaking to the Sunday Express newspaper RJ said: ''The end was peaceful and dignified, there were no theatrics. It was only later that I cried and cried".
''It wasn't the cancer that killed my father; those reports are wrong".
''Dad had actually gone into remission and the cancer was completely unrecognisable, it was too small to detect. No scan could see it. He actually died of kidney failure".
''I wanted dialysis and CPR. They said it was futile because he was a stage 4 cancer patient. I can't count how many times I'd been told that it would be a futile procedure because he had stage 4 cancer and he wouldn't make it. Yet he always came back".
''Three days before, he was sitting up and watching DVDs and then suddenly he had a seizure. He was then dosed with sedatives to deal with the side effects of his chemotherapy and his liver just couldn't process them".
''He deteriorated to the point where it started to affect his kidneys as well".
''Basically my father died of kidney and liver failure. It was a really sudden downturm'.'
Speaking about the funeral, which will take place in June, RJ added: ''We've been discussing hymns and songs. There will be some Bee Gee tracks, though we don't know which yet, and maybe Roy Orbison's Crying. My father loved Roy's music and they were great friends.''
