The Osmonds began as a barbershop quartet group with all the older brothers. I think there were five of them and later the younger boys joined, which made them seven in total. They started the band in order to raise money to buy hearing aids for their two oldest brothers, who were born deaf.
Their only sister, Marie, poor wee thing, didn't really sing with her brothers, but she went on to have a successful solo country career. They grew up a very religious family and were very clean-cut.
Handsome Donny was, by far, the most popular of the brothers and quickly became a heart-throb and front man of the Osmonds. Later, The Donny and Marie TV show took off, but it only ran for 3 years before they went bankrupt.
It seems they all went to the same dentist as they all had the same row of shiny, perfectly shaped teeth. Perhaps that is why they really went bankrupt? Tooth high in dentist bills...
Although they had a clean cut image, their family always seemed to be riddled with scandal.
Here's one of Donny and Marie's hits.
