A FUCKING COMA (CNN) -- Bee Gees star Robin Gibb is in a coma and has pneumonia, the latest turn in health issues that include a recent battle with colon and liver cancer, his representative confirmed Saturday. Doctors believe that Gibb, 62, has a secondary tumor, representative Doug Wright said, confirming a news account in The Sun in the United Kingdom. Gibb had emergency surgery in 2010 for a blocked bowel and then had more surgery for a twisted bowel, Wright confirmed. His brother Maurice died in 2003 of a twisted bowel. Brother Andy died at age 30 from a heart infection. The Brothers Gibb -- calling themselves the Bee Gees -- soared to renown as one of the most successful British groups after the 1977 film "Saturday Night Fever" starring John Travolta was built around the group's disco songs. Inducted into the Rock and Roll Hall of Fame in 1997, the Bee Gees have sold more than 200 million albums, and their soundtrack album to "Saturday Night Fever" was the top-selling album until Michael Jackson's "Thriller" claimed that distinction in the 1980s.
