I'm terribly sorry to hear that Jacques. My condolances to you and your family.
My father is battling lung cancer right now. The chemo knocked the socks off him and put him in hospital, so they stopped giving him that, then just two weeks ago they tried him on the chemo pill, which made his whole body break out in hives and rashes, so now he's off that too. I'm afraid his end will be the same as your fathers not too soon from now. What a shame.
I feel for you and hope you remember the good times you two had.
Joey
