That includes David Osmond, the son of Alan Osmond. You might also remember he auditioned for Season 8 of American Idol.
But right now, he's talking about a personal struggle. David is battling Multiple Sclerosis, the same auto-immune disease as his famous dad.
David will be speaking and singing at the Ritz-Carlton in Clayton on Wednesday at 11:00 a.m. Tickets are $75 per person and all the funds raised stay local and go directly to the almost 7,000 people in the St. Louis area affected by M.S.
