Kelvin's son has been in touch. I hope people don't mind, or think it morbid, if I pass on the information...
"My father was 66 years old and with no health problems, so it has come as a shock to us all. He took pride in giving me all the information from this site, and i didn't know if he spoke rubbish or not to you guys!
He suffered a shock heart attack at 7am this morning and leaves behind his Loving wife of 28 years, and three children, 24,26 and 29 respectively. It would be nice if you did post something.
Thank you for your kind words.
Kind Regards
Ben"
From my point of view, "Kelbo" was one of the really good guys and his contributions - public and private - will be sorely missed. 66 is no age these days and my heart goes out to his wife and family.
RIP mate.
