Hawaiian singer Don Ho [ tickets ], best known for his song "Tiny Bubbles," which he typically performed while accompanying himself on ukulele, died Saturday at the age of 76.

The cause of Ho's death has still not been released, although the Honolulu Advertiser newspaper reported that the performer suffered a heart attack early Saturday at his home in Waikiki.

Ho had suffered from heart problems in the past, reportedly undergoing an experimental stem-cell procedure in Thailand in 2005 to strengthen the muscles of his heart, which allowed him to return to his performing schedule of two shows per week at a Waikiki hotel, according to the Reuters news service. According to the Honolulu Star-Bulletin, he gave his final Waikiki performance on Thursday (4/12).

A native of Hawaii, Ho began his career in music by performing at Honey's, a bar owned by his parents. "I had no intention of being an entertainer," Ho once told an interviewer. "I just played songs I liked from the radio, and pretty soon that place was jammed. Every weekend there would be lines down the street."

It was his 1966 release of "Tiny Bubbles" that put Ho firmly into the popular consciousness and led to him playing before sold-out crowds at places like the Flamingo Hotel in Las Vegas.

Ho's record sales declined in the late '60s, but he remained a fixture in Las Vegas and on television, where he appeared in a memorable cameo on the 1972 "Hawaii Bound" episode of "The Brady Bunch."

"Everybody has to have an identity, your own original thing," he told columnist Bob Krauss of the Honolulu Advertiser in a 1995 interview. "Our thing was the way you sit around the garage on a weekend--play music, joke around. We just took it to the showroom."

In one of his final studio performances, Ho appeared on a 2002 anthology album, "When Pigs Fly: Songs You Never Thought You'd Hear," singing a version of Peter Gabriel's "Shock the Monkey."

"Of all the musicians on the record, I wanted most to work with him again and we were talking about doing a rock covers album with songs like 'Whole Lotta Love' for my label," said a statement issued by Cevin Soling, who produced and organized the anthology.

"He was a very sweet man and really loved by everyone around him," Soling added.
