In a January 1982 broadcast of the
Trinity Broadcasting Network television program
Praise the Lord hosted by
Paul Crouch, it was claimed that hidden messages were contained in many popular rock songs through a technique called
backmasking. One example of such hidden messages that was prominently cited was in "Stairway to Heaven". The alleged message, which occurs during the middle section of the song ("If there's a bustle in your hedgerow, don't be alarmed now...") when played backward, was purported to contain the Satanic references: "Here's to my sweet Satan / The one whose little path would make me sad whose power is Satan, / He'll give you, he'll give you 666 / There was a little tool shed where he made us suffer, sad Satan."
Following the claims made in the television program, California assemblyman
Phil Wyman proposed a state law that would require warning labels on records containing backmasking. In April 1982, the Consumer Protection and Toxic Materials Committee of the
California State Assembly held a hearing on backmasking in popular music, during which "Stairway to Heaven" was played backward and self-described "neuroscientific researcher" William Yarroll claimed that the human brain could decipher backward messages.
