According to Patrick Humphries and Chris Hunt's 1985 book
Bruce Springsteen: Blinded By The Light, "Tex Vinyard, The Castiles' manager, liked the instrumental so much that he got them to include it into their stage performances, circa 1966. No absolute dates are known.
Blinded By the Light was an essential bible for Bruce Springsteen fans like us. Co-authored by Patrick Humphries and Chris Hunt, the 1985 Springsteen book paired biography — handled by Humphries — with Hunt's "The Bruce Files," the sort of stuff that might have been touched on in an appendix anywhere else but here comprised more than half the book. Clearly from the obsessive brain and collection of a hardcore fan, Hunt's portion of Blinded gave us a concert chronology, discography, bootleg guide, listings of Springsteen compositions (released and unreleased) and covers, with images reproduced from a hoard of posters, memorabilia, ticket stubs, records and clippings.
