Which singer’s death will be the most mourned?

A funeral is scheduled for Wednesday for former Pink Floyd member Roger Waters, who died at the age of 74, in the city of Pittsburgh, Pennsylvania.

The concert and funeral were announced in the Pittsburgh Post-Gazette, which said Waters was diagnosed with Alzheimer’s disease.

The newspaper said he was last seen in September at his home in Pittsburgh.

The death of Waters, a longtime supporter of Democratic presidential nominee Hillary Clinton, comes just days after a report from the Associated Press said the singer suffered from dementia.

Waters’ death will mark the latest loss of a rock star in recent years, and follow several others in the rock world, including former Metallica bassist Robert Plant and singer Tom Petty, who was found dead in a Los Angeles hotel room in August.
