I was surprised when I saw this, because I didn't even know that there was a feud between Twisted Sister and Krokus. Here's what happened...
In 1982, Dee Snider's wife was hired to make the costumes for Krokus for an upcoming tour. Krokus hated them, refused to pay her, and supposedly threatened her. NOT COOL!
Dee and the rest of Twisted Sister hve been pissed off at Krokus ever since, and Dee has every right. That's his wife. Who knows what Krokus was waiting for, but they finally apologized and publicly offered to end the feud.
Dee responded that he'll end the feud... if his wife says it's okay. If she can forgive Krokus, then he'll move on. Smart man.
