Ho, 75, known for his signature tune "Tiny Bubbles," is recovering at a hospital in Thailand, Tuesday, Dec. 6, 2005, after undergoing an experimental stem cell procedure on his ailing heart. The treatment, which has not been approved in the United States, involves multiplying stem cells taken from his blood and injecting them into his heart in hopes of strengthening the organ, according to agent Ed Brown, a close Ho friend.
