The 83-year-old singer, who announced over the weekend that he is battling bladder cancer, has had a slew of hits, including "Moon River" from "Breakfast at Tiffany's."

Andy Williams announced Saturday that he is battling bladder cancer.

“I do have cancer of the bladder,” the 83-year-old singer told the crowd attending a concert at his Moon River Theatre in Branson, Mo. “But that is no longer a death sentence. People with cancer are getting through this thing.”

Williams, who has had a lengthy career, has been appearing in Branson on a regular basis since 1992, typically performing two shows a day, six days a week for nine months a year.

The optimistic singer surprised the crowd Saturday with the news during his 2011 Andy Williams Christmas Show, but continued that he plans to return to the theater next year to celebrate his 75th year in show business.

“I’m going to do the shows I’ve planned to do,” he said.

Williams has racked up a slew of hits over his career, including several theme songs from movies as well as Christmas carols still played every December. Here are his five most iconic songs:

1. "Moon River": The singer is perhaps best known for the theme song from the 1961 movie Breakfast at Tiffany's starring Audrey Hepburn and George Peppard. The song, composed by Johnny Mercer (lyrics) and Henry Mancini (music), won an Oscar.



2. "Love Story: Where Do I Begin?": Williams continued singing movie theme songs with this track from the 1970 movie Love Story, starring Ali MacGraw and Ryan O'Neal.



3. "Speak Softly, Love": Yet another movie theme, this one for 1972's The Godfather, starring Marlon Brando and Al Pacino.



4. "Days of Wine and Roses": Another theme, from the 1962 movie of the same name. Like "Moon River," it was written by Mancini with lyrics by Mercer, who received another Oscar for their work.



5. "It's the Most Wonderful Time of the Year": Williams has recorded a slew of Christmas songs, but this one -- which still gets significant radio airplay every year around the holidays -- has become synonymous with the singer.
