Jerry Lee Lewis has canceled his July 1st show in Nashville.
Though his Facebook page says he's "progressing miraculously in his recovery following the recent stroke," dropping out of a show six weeks away has to raise doubts about his condition.
The voice of '50s classics such as "Great Balls of Fire" and "Whole Lotta Shakin' Goin' On" "is continuing his rehabilitation and his team expects a full recovery, as well as a return show in Nashville in the very near future."
Lewis will turn 84 in September.
