Songfacts®:

• According to Night Ranger drummer Kelly Keagy, "Let Him Run" was the first song the band ever wrote, although it wasn't released until their second album, Midnight Madness, where it was used as the last track.
  
  "It's a relationship song," Keagy told Songfacts. "You've got to let that person go. It's time to let them go – they're hurting you too much. Let him go, and he'll come back."
• The song was written by Keagy, bass player Jack Blades, and guitarist Jeff Watson. Keagy and Blades were the vocalists and primary writers in the band, but Watson also made contributions, including the distinctive acoustic guitar riff on this track.
• There is no drums or bass on this track, which meant that Kelly Keagy could come out from behind his kit to sing this live, and Jack Blades could put down his bass to join him on harmony vocals. When they did the song live, they would extend the intro with Jeff Watson and Brad Gillis dueling on acoustic guitars.
