Country legend Johnny Cash was in serious but stable condition Monday (Feb. 12) at Nashville’s Baptist Hospital, a hospital spokeswoman tells country.com. The 68-year-old singer was admitted Sunday morning and is being treated for pneumonia. A bout with the same disease in 1998 put Cash in a coma and nearly claimed his life. In 1997, he was diagnosed with Shy-Drager syndrome, a neurological disorder. A year ago doctors told Cash he was misdiagnosed with Shy-Drager and actually suffers from autonomic neuropathy, a disease that affects the central nervous system, Lou Robin, the singer’s manager, told country.com in January. In recent months Cash has been planning a new album with producer Rick Rubin. His current project, American III: Solitary Man, is nominated for two Grammy awards.
