"After KISS played a concert in Flint, Michigan, in 1975, Peter and I were in a limousine together, and he was trying to sing something he called 'Beck,' about a girl named Becky. I suggested that he change the name to Beth, both because it was a little easier to sing and because it would
eliminate any possibility of misunderstanding that it was about Jeff Beck" (italics mine)--Gene Simmons, in 'Kiss and Make-Up.'
