Carol Haney and Larry Blyden were married from 1955-1962, divorcing two years before Haney's death. Haney didn't die of cancer. She was an alcoholic and had diabetes; she died of pneumonia compounded by her drinking and chronic disease. She was only 39--very sad.
Blyden was one of the biggest stars on Broadway right up until his death, at 49, while on vacation in Morocco just a few weeks after he left the original production of ABSURD PERSON SINGULAR. At the time, he was preparing to host the game show SHOWOFFS, which ended up being hosted by Bobby Van.
Sadly, one of Haney and Blyden's two children, Josh, died young as well, at 42.
