As reported on country.com Wednesday (March 21), Loretta Lynn is battling pneumonia at a hospital near her home in Hurricane Mills, Tenn., forcing her to cancel her scheduled appearance on tonight's (March 22) "Tribute to Johnny Russell." Garth Brooks, Vince Gill, Ricky Skaggs, Roy Clark, George "Goober" Lindsey, John Conlee, Connie Smith, Bill Carlisle and the Oak Ridge Boys are among those who will be on hand to salute Russell. A member of the Grand Ole Opry since 1985, Russell is the writer of such hits as "Act Naturally," "Let's Fall to Pieces Together," "You'll Be Back (Every Night in My Dreams)," "Makin' Plans" and "Got No Reason Now for Goin' Home." Ralph Emery and Gill will co-host the event at the Grand Ole Opry House in Nashville. The aim of the concert is to raise funds to help cover Russell's continuing medical expenses. "Johnny inducted me into the Opry 11 years ago, and that's still the highest honor I've received in this business" Brooks said in a press statement. "I love him, I'm a fan, and if this show can help him get better, I'm all for it." Those who wish to make contributions can make their checks out to "Johnny Russell Tribute" and send them to 2607 Crump Drive, Nashville, TN 37214.
