Singer Gary Wright died at 80 years old on Monday after years of health issues, according to his family.

Wright’s son, Justin Wright, told TMZ that the musician died Monday morning at his home in Palos Verdes Estates, California, with his family and loved ones by his side.

The singer-songwriter was diagnosed with Parkinson’s Disease more than five years ago and, shortly after that diagnosis, also learned he had Lewy body dementia. Wright’s Parkinson’s worsened over the past year and ultimately prevented him from speaking or moving around on his own, according to his son.

Nurses working in Wright’s home told the family in recent days that he was entering his final stage, per the TMZ report.
