“Blinded by the Light” is a song written and originally recorded by Bruce Springsteen which first appeared on his 1973 debut album Greetings from Asbury Park N.J.. A cover by British rock band Manfred Mann’s Earth Band reached number one on the Billboard Hot 100 in the United States in February 1977 and was also a top ten hit in the United Kingdom, New Zealand and Canada.

Manfred Mann’s Earth Band’s recording of the song features several changed lyrics. The most prominent change is in the chorus, where Springsteen’s “cut loose like a deuce” is replaced with “revved up like a deuce.” This is commonly misheard as “wrapped up like a douche” (the V sound in “revved” is almost unpronounced, and the S sound in “deuce” comes across as “SH” due to a significant lisp). Springsteen himself has joked about the controversy, claiming that it was not until Manfred Mann rewrote the song to be about a feminine hygiene product that it became popular.
