カイ・ハンセン
Weikath is one of the founding members of Helloween, along with Kai Hansen (vocals/guitar), Markus Grosskopf (bass), and Ingo Schwichtenberg (drums). He had been one of only two original members still active in the band, the other being Markus Grosskopf, until Kai Hansen and Michael Kiske rejoined in 2016. Weikath integrated the first Helloween line up in 1982. By 1984, the band had signed a deal with Noise Records and recorded two songs for a Noise compilation record called "Death Metal". On that album, he was responsible for the song "Oernst of Life."
