NEW YORK (AP) — Even frequent David Bowie collaborators Nile Rodgers and Brian Eno had no idea he was sick. Rodgers says he suspected something was up with Bowie a few years ago when Bowie presented Rodgers with an award but had to give it by film. Rodgers says Bowie was charming and big-hearted but Rodgers could see he was not well. Rodgers says he didn’t want to pry because everyone deals with their health in their own way. Eno tells Rolling Stone magazine Bowie sent him an email just a week ago that was full of inside jokes. He says it ended with Bowie saying, “Thank you for our good times, Brian. They will never rot.” Eno says he realizes now Bowie was saying goodbye.
