Legendary singer Don Ho recovering in hospital.

Legendary Hawaiian crooner Don Ho was recovering in an intensive care unit at a Thailand hospital Tuesday following an experimental stem cell procedure on his ailing heart, his spokeswoman and a close friend told The Associated Press.

Ho, 75, known for his signature tune "Tiny Bubbles," underwent a new medical procedure that has not been approved in the United States. It involves multiplying stem cells taken from his blood and then injecting them into his heart, in hopes of regeneration.

"He came through the procedure with flying colors," agent Ed Brown, a close Ho friend, said in a telephone interview from his home in Malibu, Calif. "His vitals are excellent. Everything seems to be where it's supposed to be and everyone is quite happy.

"However, it's premature — because he is in ICU — to give you any statement of certainty.". . . . . . .Full Story
