Sheryl Crow has benign brain tumor Singer Sheryl Crow and her son Wyatt attend the premiere of the animated motion picture comedy "Cars 2," at the El Capitan Theatre in the Hollywood section of Los Angeles on June 18, 2011. LAS VEGAS, June 5 (UPI) -- American singer-songwriter Sheryl Crow says she has been diagnosed with a benign brain tumor after forgetting the lyrics to some of her hits while performing. I worried about my memory so much that I went and got an MRI. And I found out I have a brain tumor," Crow, 50, told the Las Vegas Review-Journal. And I was, like: 'See? I knew there was something wrong,'" she said. I haven't really talked about it. In November, I found out I have a brain tumor. But it's benign, so I don't have to worry about it. But it gives me a fit. The newspaper said Crow's condition doesn't seem to be slowing her down. She is working on a new album, as well as writing a stage musical version of "Diner" with Barry Levinson, the writer-director of the 1982 film.
