Singer Robert Goulet died Tuesday at a Los Angeles hospital at the age of 73. The Broadway star had been waiting for a lung transplant after being diagnosed last month with a rare form of pulmonary fibrosis — a deadly illness that scars the lungs and ultimately affects the ability to breathe.

“His incredible voice will live on in his music, and as Bob so brilliantly sang, ‘There will be another song for him and he will sing it,’ for God now has another singing angel by his side,” Goulet’s friend Wayne Newton said in a statement.

Goulet’s passing marks the music world’s second loss this week. Grand Ole Opry star Porter Wagoner died of lung cancer on Oct. 28 at the age of 80. A long-running fixture in Nashville, Wagoner is credited with launching Dolly Parton’s career when he introduced her on The Porter Wagoner Show as the program’s “dumb blonde.” Parton remained a close friend of Wagoner and even visited him in the hospital prior to his death.
