Legendary crooner Andy Williams announced over the weekend that he has been diagnosed with bladder cancer.  The 83 year-old made the revelation at his Moon River Theatre in Branson, Missouri, but added that cancer is not a death sentence anymore.  Williams said that he plans on making all his scheduled performances, including his annual Christmas show at the Moon River.  Check out a clip of Williams from last year's Christmas show performing a medley of songs including his 1957 No. 1 single, "Butterfly," below.
