The three-time Grammy Award winner, who withdrew from making music in the mid-1980s and lived outside the public eye since, died on March 30 in Los Angeles.

His death came as the public has drawn inspiration from his music during the coronavirus pandemic, with health care workers, choirs, artists and more posting their own renditions on "Lean on Me" to help get through the difficult times.

"We are devastated by the loss of our beloved, devoted husband and father. A solitary man with a heart driven to connect to the world at large, with his poetry and music, he spoke honestly to people and connected them to each other," the family statement read. "As private a life as he lived close to intimate family and friends, his music forever belongs to the world. In this difficult time, we pray his music offers comfort and entertainment as fans hold tight to loved ones."
