Legendary glam rockers KISS were left a man down at a recent Californian concert when vocalist/rhythm-guitarist Paul Stanley suffered a heart scare.

According to the band's official website, the singer's heart "spontaneously jumped to 190 plus
beats per minute" during a routine sound-test, staying that way for over an hour.

Though not thought to be life-threatening by paramedics, Stanley was unable to participate in the show, leaving KISS to perform as a threesome for the first time in their illustrious career.
