The original Metroid version differed depending on whether the game was the NES or Famicom Disk System version. In the NES version, there is a simple "whoop whoop" sound, while the Famicom version features a screeching siren. The NES version also features an uplifting part that was removed in later versions, which made it sound closer to the original Japanese theme. The Famicom version is included on the Super Metroid: Sound in Action CD, titled Escape! Tanaka remixed the theme as part of a medley with Samus Aran's Appearance Fanfare and Brinstar on the single Kid Icarus / Metroid Original Soundtrack Orchestra Version. On this single the theme is titled During Escape BGM, and it retains the uplifting portion from the game on NES.
