On 4. April 1975, Paul Stanley performed the concert at the Nordic Ice Arena in Hartland, USA, with sunglasses. Right before this concert, Stanley developed a bad eye infection that prevented him from putting on any makeup near his eyes. There’s also a rumour that following the April 4. concert, Stanley’s eye was bothering him so much that he went to McPherson Hospital in Howell to have it checked out. With all of the rest of his makeup still on. He also wore sunglasses for Kiss’ April 6. concert in Washington, D.C.
