"Andy's the one that started it for us," they said. "He was the whole beginning of it. And what a voice! We grew up together. If there was anything stable in our lives, it was being on Andy's show and with him."

Throughout the 1960s and 1970s, Andy Williams popularized several songs from motion pictures. Among them were his signature tune "Moon River" from "Breakfast At Tiffany's," as well as the themes to "Love Story," "Dear Heart," "The Godfather" and "Days Of Wine And Roses."

Andy Williams recorded more than 800 songs in English, Spanish, Portuguese, French, Italian, German and Japanese. His Christmas albums and compilations were among his bestselling recordings.

Williams’ popularity continued long after his chart success faded. In 1992, he opened the Andy Williams Moon River Theater in Branson, Missouri where for years he performed six nights a week. He once commented on his accomplishments and the changing trends in the music industry.

"I had my time selling millions of records and the record business is a very young business. Most of it's sold, 90 percent of it, I think, is sold to kids between 10 and 20 [years old]," Williams said. "You're not expected to be 'hot' [popular] all the time."

Andy Williams was respected for his charity work, which raised money for the Children's Asthma Research Institute and Hospital and the Robert F. Kennedy Memorial Foundation.

In 2007, he released his final studio album, “I Don’t Remember Ever Growing Up.” His autobiography, “Moon River and Me: A Memoir,” was published in 2009.
