I agree, doesn’t sound like a covid death.
For three weeks including Christmas, I had an upper respiratory infection. It included many days of laryngitis. I tend to slide quickly into bronchitis, but didn’t. What I did experience, was an odd, almost choking type, dry cough. It was as if something was choking my windpipe and esophagus. On Christmas night I coughed and couldn’t breathe anymore. When my breathing returned, I was relieved. It felt like the wind was knocked out of me and my diaphragm was paralyzed. Everyone of us tested Covid negative that morning.
Perhaps the singer had what I had on an already weakened system.
