Songfacts®:

• Bruce Springsteen originally wrote this melodic ballad for the 2001 movie Harry Potter and the Sorcerer's Stone, but it was never used. The public finally got to hear the song when it was included on the soundtrack of the 2019 Boss-inspired film Blinded By The Light.
  
  When Simon Mayo of the BBC asked Springsteen why it wasn't used in the Harry Potter movie, he replied, "You'd have to ask them." Springsteen added that "I'll Stand By You" is a "big ballad" that he wrote for his eldest son. "(It's) very uncharacteristic of something I'd sing myself," he said. "At some point I'd like to get it into a children's movie of some sort."
• Blinded By The Light tells the true coming-of-age story of a Pakistani Muslim teenager living in 1980s England whose life is changed after he discovers the music of Springsteen. The Boss allowed 12 of his songs to be used on the soundtrack, including this previously unreleased track.
• Bruce Springsteen's eldest son, Evan, would have been 10 or 11 years old when his father wrote this song for him.
• In early 2001, during post-production on Harry Potter and the Sorcerer's Stone, Springsteen offered "I'll Stand By You" to director Chris Columbus. The director was floored. "My f---ing heart leaped into my throat," Columbus recalled. "Here was my chance, my opportunity to finally have a Bruce song in one of my films."
  
  Columbus even envisioned it playing over the closing credits, sending young audiences home with The Boss's voice echoing through the theater.
  
  But Hogwarts and Asbury Park were never meant to meet. The song was rejected due to a clause in JK Rowling's contract that forbade the use of commercial music in any Harry Potter movie. Columbus later admitted that even without the rule, it might have felt jarring. After two hours steeped in British actors and John Williams's stately orchestration, Springsteen's gravely New Jersey baritone would have shifted the tone "back across the pond, back to America."
• Not one to let a good tune sit idle, Springsteen later passed "I'll Stand By You" to Latin pop star Marc Anthony, believing he could bring out the song's soulful core. Anthony planned to include it on his 2002 album Mended, but the track never made the final cut, and for more than two decades, the song disappeared into Springsteen lore, until it was included on the Blinded By The Light soundtrack.
• The song was later included on Twilight Hours, one of seven previously unreleased albums included on the 2025 box set Tracks II: The Lost Albums. Produced by Springsteen and longtime collaborator Ron Aniello, Twilight Hours gathers what Bruce calls "romantic, lost-in-the-city songs," lush, orchestral tunes that echo the crooners and pop stylists of the 1960s. These songs were mainly recorded during the Western Stars sessions.
  
  "Bruce was writing all these songs with a kind of Burt Bacharach feeling," Aniello told Uncut magazine. "I remember him mentioning artists like Andy Williams. He'll immerse himself in a certain type of music as a listener and then apply that to his work. Twilight Hours will probably be the most surprising record for his fans, but it's artful, cinematic, and really cool."
  
  Springsteen included "I'll Stand By You" on Twilight Hours because its sweeping, romantic tone fit the album's noirish, orchestral aesthetic.
