The singer was placed on a respirator for a while, but is now breathing on his own in the intensive care ward and expected to recover fully. Doctors at his Forth Worth-area hospital have determined he suffered no spinal or brain damage in the fall, and may be allowed to return home in a few days. Nonetheless, Johnny’s planned Aug. 20 show at the North Texas State Fair & Rodeo in Denton has been canceled. Johnny’s many 1970s hits include the chart-toppers “Riding My Thumb to Mexico” and “Love Put a Song in My Heart.”
