Doctors warned the couple that future children had a higher chance of having hearing loss, but George and Olive wanted a large family.
George formed a barbershop quartet consisting of Alan, Wayne, Merrill, and Jay, and eventually got them booked at Disneyland, where the boys caught the attention of Walt Disney himself, and Andy Williams's father.
The brothers eventually left Williams and were regulars on the second incarnation of The Jerry Lewis Show (1967-1969) before launching a successful recording career.
The siblings - including Donny, Marie, and Jimmy as solo artists - scored several hits, The Osmonds' biggest being "One Bad Apple", which climbed to #1.
2001's Inside the Osmonds (produced by Jimmy) depicted the siblings' egos and their frustration at not being taken seriously as artists by the music industry, George's fiscal mismanagement, and the quest to establish a "new Hollywood" in Utah as leading to the family's downfall.
