LOS ANGELES - Robert Goulet, the handsome, big-voiced baritone whose Broadway debut in "Camelot" launched an award-winning stage and recording career, has died. He was 73.

The singer died Tuesday morning in a Los Angeles hospital while awaiting a lung transplant, said Goulet spokesman Norm Johnson.

He had been awaiting a lung transplant at Cedars-Sinai Medical Center in Los Angeles after being found last month to have a rare form of pulmonary fibrosis.

Goulet had remained in good spirits even as he waited for the transplant, said Vera Goulet, his wife of 25 years.

"Just watch my vocal cords," she said he told doctors before they inserted a breathing tube.

The Massachusetts-born Goulet, who spent much of his youth in Canada, gained stardom in 1960 with "Camelot," the Lerner and Loewe musical that starred Richard Burton as King Arthur and Julie Andrews as his Queen Guenevere.

Goulet played Sir Lancelot, the arrogant French knight who falls in love with Guenevere.

He became a hit with American TV viewers with appearances on "The Ed Sullivan Show" and other programs. Sullivan labeled him the "American baritone from Canada," where he had already been a popular star in the 1950s, hosting his own show called "General Electric's Showtime."
