Joni Mitchell's unable to speak post surgery: David Crosby

"Big Yellow Taxi" hitmaker Joni Mitchell is not able to speak after her recent surgery for brain aneurysm, says singer David Crosby.
It was confirmed, last month, that Mitchell had suffered a brain aneurysm, when she was found unconscious in March.
Crosby said Mitchell, 71, will struggle to recover from the "traumatic brain injury," reported the Huffington Post.
"Nobody found (Mitchell) for a while. She took a terrible hit. To my knowledge she is not speaking yet... She's going to have to struggle back from it the way you struggle back from a traumatic brain injury.
"She's a tough girl, and very smart. So, how much she's going to come back and when, I don't know and I'm not going to guess. I love her. She's probably the best of us - probably the greatest living singer-songwriter. I think we're all holding our breath and thinking a good thought, hoping that it's going to turn out OK," he said.
