Not a good weekend for current or former members of the rock band KISS.

FOX's Rich Denison reports:

KISS singer-guitarist Paul Stanley and former guitarist Ace Frehley each dealing with medical issues:

(KISS) "I wanna rock and roll all night."

Stanley writes on his Facebook page he tore his bicep tendon and had surgery. Adding, he'll be "ready to rock" before the KISS tour begins:

(KISS) "I'm back, back in a a New York groove."

Frehley's website reports he was admitted to a hospital for exhaustion and dehydration after Friday's show in Wilkes-Barre, Pennsylvania. Frehley had called off a show in New Hope, Pennsylvania, a week ago, saying a band member was sick.
