Robin Gibb's touring - including a charity appearance in Christchurch - may have cost him his life.
The Bee Gees singer missed scans that may have detected his cancer so he could tour. He died of liver and colon cancer in May.
His wife, Dwina told the Daily Mail he went against doctors' advice to have his cancerous cells properly checked, instead choosing to tour, including a charity performance after the Christchurch earthquakes.
Robin Gibb performed on a solo tour of Australia and New Zealand, including appearances in Christchurch, Wellington and Auckland, in late 2010.
Cancerous cells were initially spotted after surgery for intestinal blockage in October 2010.
Dwina told the Daily Mail newspaper: "He didn't want to stop and I said, 'Please just have the scan.' Despite all his wonderful ways, Robin could be very stubborn and he never liked bad news - he just didn't want to know.
"He went to do a show in New Zealand as they'd just experienced an earthquake. Maybe it was very important for him to do that show, but it was still important for him to have his scans."
By the time he had a check up, the tumour had started to spread to nearby blood vessels.
Robin's brother, Barry - the only remaining member of the Bee Gees - plans to tour in memory of his three brothers.
Barry said: "I will live on the music. And no matter what stage I'm standing on, my three brothers will be standing there with me."
