If anyone saw his performance of Rainbow Connection with Kacey Musgraves last night at the 2019 CMA Awards there was plenty to be concerned about. He had very noticeable problems breathing and he really couldn’t sing his part. Instead, he “talked” his way thru the song and struggled breathing even when he wasn’t the one singing. I know he has had lung related problems before but this was especially troubling to see for this American treasure. Kind thoughts for Willie.
