Eagles rocker Glenn Frey has assured fans old friend and collaborator Linda Ronstadt is doing well after she was forced to skip her induction into the Rock and Roll Hall of Fame on Thursday (10Apr14) due to ill health. The Blue Bayou singer, 67, was a member of the Class of 2014 feted during a ceremony in Brooklyn, New York, but she was a no-show after recently revealing her battle with Parkinson's disease had made travelling cross-country from Los Angeles too difficult for her. But Frey, who did turn out to the event to honour his pal, insists devotees have no need to worry as she is feeling good otherwise. The rocker says, "I spoke to her a couple of days ago... She's got a very bad back and she can't sit for too long without lying down and she can't lie down for too long without sitting up. But she's doing fine... "At this time, I just think it was a little much to ask her to fly across the country for this (induction)." In Ronstadt's absence, Stevie Nicks, Sheryl Crow, Carrie Underwood, Bonnie Raitt and Emmylou Harris paid tribute to the singer by performing a medley of her hits for the Barclays Center crowd.
