Singer Wayne Osmond dies at 73

Wayne Osmond, the singer of the American family pop group the Osmonds, has died at the age of 73, his brother announced Thursday.

Osmond passed away at a hospital in Salt Lake City, Utah, after suffering a "massive stroke," his brother Merrill Osmond said in a Facebook post.

"I've never known a man with more humility. A man with absolutely no guile," the post read. "An individual who was quick to forgive and had the ability to show unconditional love to everyone he ever met."

Wayne Osmond was the fourth of nine siblings raised in a Mormon household in Ogden, Utah.

The siblings' career began in the 1950s when Wayne, Alan, Merrill, and Jay performed as a barbershop quartet.

In 1961, the four brothers were discovered singing at Disneyland. They gained exposure on television shows, and their popularity grew. Brothers Donny and Jimmy eventually joined, as did their sister Marie.

In 1971, the group reached the height of their fame with the release of "One Bad Apple." The song spent five weeks at No. 1 on the Billboard Hot 100, according to People magazine.

Shortly afterward, the band went their separate ways. Jimmy pursued a solo career, while Donny and Marie, now aged 67 and 65, began performing as a duo.

Wayne Osmond married Kathlyn White, a former pageant queen, in 1974. They had five children together.

Wayne Osmond experienced a number of health issues over the years. In 1997, he was diagnosed with a brain tumor and lost nearly all of his hearing due to the treatment, People reported.

Then, in 2012, he suffered a stroke that left him unable to play the guitar.
