In Scott Teal's Whatever Happened To... #41 newsletter, Ed 'Moondog' Moretti explained that Krupp had difficulty separating his wrestling character from real life. "Killer Karl Krupp... what a nice guy. I love him to death, but I think he actually believed he was Killer Karl Krupp. He had a partner in the Maritimes named Hans Hermann, who wrestled in Calgary as Butch Moffitt, the Jackal. We were at home and Krupp was telling him ... this is in a German accent now ... 'You cannot go outside. You cannot be seen at the beach with your family. You are a German wrestler and need to live this gimmick twenty-four hours a day if you want to get over."
In 1980, Krupp came to Memphis where he eventually joined Jimmy Hart's First Family of Wrestling stable and tangle with Jerry Lawler. He returned before long to Atlantic Canada, however, where he had a memorable run in Atlantic Grand Prix Wrestling, holding the European Title and feuding with The Great Mulumba and Hercules Cortez. In the mid-'80s, near the end of his career he toured New Zealand ( as mentioned in yesterdays post ), the high point being winning the British Commonwealth title from Steve Rickard.
