The Grammy-winning singer-songwriter has been battling glioblastoma, an aggressive and often deadly brain cancer, since late 2023. He plans to keep fighting.

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.
