A Grammy-winning singer who was diagnosed in December 2023 with glioblastoma—the most aggressive and rapidly progressing type of brain cancer—began showing signs that something was wrong the previous month.

His daughter, Taryn, talked to People, too, and she revealed that the singer displayed several symptoms in the days leading up to his diagnosis. One of the signs that she said was “super weird,” came during a bowling outing in 2023. She said her father bowled out of turn three times.
