"He was in the process of working on a book on the Cemetery Circuit. I went in to see him this week ... and he said "I'm just editing the book'. It's still sitting on his computer so we'll see what comes of that."
Whitham also worked as a morning sports host on Newstalk ZB, a Midweek columnist, Oceanview Speedway commentator, and back in the 1970s did television work during the Marlboro Series.
Suzuki Series organiser Allan Willacy said he was visiting Whitham to get his latest written work for this year's Cemetery Circuit programme when the great former Grand Prix competitor Ginger Molloy phoned to ask about a third-place rider from a 1972 race.
"And Ray could tell him. That's the amazing-ness of Ray," said Willacy. "It's the small details that he kept. Could tell you if they'd been there and what they did. It's the history that we've lost."
After being diagnosed with cancer in September, Clive Whitham said his brother just wanted to stay active and make the most of his remaining time, trying to get to as many of the summer races as possible. "He never wanted it to drag out."
Using oxygen, it was arranged for Whitham to travel back to Manfeild last weekend for Round 2 of the Suzuki Series, saying goodbye to old friends while also getting to meet the United Kingdom's world sidecar champions in Tim Reeves and Mark Wilkes.
"It was wonderful, he had a really good day and I think he was holding out for that," said Clive Whitham.
The funeral service will be held at 1.30pm on Tuesday at the Dempsey and Forrest Funeral Home, on Guyton St. Whitham is survived by his two living brothers and sister.
