Williams, whose cause of death was related to his battle with bladder cancer, had a 75-year entertainment career, which included a 1974 appearance on Broadway with composer and pianist Michel LeGrand.

Williams' recording career yielded numerous gold and platinum records – including the iconic "Moon River" – and he is also well known for his television appearances on the Emmy Award-winning The Andy Williams Show.

He is survived by his wife Debbie, and his three children from a previous marriage, Noelle, Christian, and Robert.
