So Bruce Springsteen wrote the original version of “Blinded By the Light”. But Manfred Mann’s version was the one that was a huge hit. And Mann’s version does say “wrapped up like a douche” (versus Springsteen saying “revved up like a duce”).
I saw an interview with Springsteen where he speculated that was the biggest writing mistake he’d made. If only he’d said “wrapped up like a douche”, maybe his version would have sold better.
