Robin Gibb was heartbroken to miss the launch of his new classical project in London on Tuesday (10Apr12) as he is still fighting a lung infection in hospital, according to his son.
The veteran singer was diagnosed with liver and colon cancer last April(11) and, after undergoing an intense course of weekly chemotherapy sessions, he told fans in March (12) the disease is now in remission.
He was admitted to a clinic earlier this month (Apr12) after falling ill with pneumonia and was forced to miss out on London's Titanic Requiem concert, which he co-wrote the music for.
Gibb's son Robin-John reveals the star was devastated not to be able see the his classical project come to fruition.
Speaking on BBC Breakfast, he says, "He is still in hospital, he's fighting a lung infection and of course - as a lot of people who have had family members or friends who have been through a cancer bout, they know there are a lot of periphery problems afterwards they have to deal with.
"God willing, and we are all praying for him. That he makes a speedy recovery... "The one place he really wanted to be in two and and a half years and he couldn't be, and it was heartbreaking..".
However, Robin-John plans to watch a recording of the concert with his father as soon as he is well enough, adding, "He'll be able to see it.
"It was recorded and live streamed. We'll have a good knees up and watch it together".
