The legendary crooner Andy Williams has died aged 84. The singer, who was one of the world’s most popular artists of the 1960’s had been battling bladder cancer for a year before he passed away at his home in Branson, Missouri.

He is survived by his wife, Debbie, as well as his three children, Robert, Noelle and Christian. The family have asked that donations are made to the Bladder Cancer Advocacy Network, in lieu of flowers. His death was confirmed by his publicist, Paul Shefrin, CBS News reports.

One of Williams’ signature tunes was the Johnny Mercer and Henry Mancini-penned ‘Moon River’ (which featured on the soundtrack to Breakfast At Tiffanys, starring Audrey Hepburn). On Twitter, some fans have paid their respects by quoting the lyrics of the song and bidding ‘farewell’ or ‘rest in peace’ to “our huckleberry friend.” As well as his recording career, Andy Williams became well-known and loved throughout the 1970s and 1980s, for his Christmas TV specials. He was also a regular host of awards shows, such as the Grammys, the Golden Globes and the People’s Choice Awards.

Williams married Debbie Meyer in 1991. His previous wife, the French-born dancer Claudine Longet is the mother of his three children. After she and Andy divorced in 1975, she was charged with fatally shooting her boyfriend. Williams made the headlines at the time by standing by her side throughout her public trial.
