David Cook never took credit for any song he used. The reason he wears the cancer bracelet is because his brother is dying from brain cancer and was flown in for the show last week. I tried to explain this already to whats-his-name, but to no avail. You have more patience than I!!
Yeah I know about his brother. I will admit that I have found Cooks attitude at times to be a bit offputting. But when you look at his overall talent, the attitude is a bit easier to take.
