Joni Mitchell was a tragic sight at Elton John's
70th birthday party in Los Angeles on March 25 — as the 73-year-old folksinger struggled to get out of her wheelchair and make it into the event! The "Big Yellow Taxi" songstress suffered a brain aneurysm in 2015. She was rushed to the hospital
after being found unresponsive at her home, and required extensive physical therapy. Fellow veteran folkie Judy Collins later reported that Joni had been "making good progress," but the legendary singer is still suffering a variety of physical ailments, including a bizarre disease that Joni has described as "a killer" — even while doctors doubt its existence!
