Guitar Hero

• The song "Spanish Castle Magic" was recorded with vocals, though they are not present in the final game. The song can be sampled with vocals intact at the official Guitar Hero website. Why the vocals were removed from the song has been said to be that the Hendrix estate do not wish for Hendrix to be impersonated.Template:Fact
• While waiting for a song to load, a loading screen is presented with an image of an amplifier. The amp has three volume knobs, each of which turn to 11. This is a reference to the 1984 "rockumentary" This Is Spinal Tap, in which an amplifier is discussed for its apparent ability to go to 11 rather than simply 10. Furthermore, one of the random loading screens displays the reference 'Eleven IS louder than ten'. Subsequently, the song "Tonight I'm Gonna Rock You Tonight" by Spinal Tap was featured in Guitar Hero II.
• Though many of the loading screens give the player brief playing tips and hints, many of them are also jokes about rock'n'roll culture. One of the screens reads: "They don't really want you to play Freebird, they're just heckling you." This is a reference to the Lynyrd Skynyrd song "Free Bird" and its frequent request at concerts. Ironically, "Free Bird" became a playable song in Guitar Hero II, with a rather self-referencing response: "Fine. They're not just heckling you this time. Sigh."
• Watching the credits in their entirety rewards the viewer with a number of messages, one of them asking the player if they've started playing a real guitar yet. A similar suggestion can be found for attaining Guitar God status on any of the difficulty settings in career mode.
• After completing all songs on the expert difficulty, the player receives the "Battle Axe" guitar. At the Guitar Select Screen, the info box next to the Battle Axe states "Judge this race not by its remains". This is very similar to one of the lines in Genesis' "Watcher of the Skies" which states "Judge not this race by empty remains".
• At the song select screen, if you scroll to the bottom, there is a graphic with the letters PMRC crossed out. This is a reference to the Parents Music Resource Center (PMRC).
• At the character select screen, when the Grim Rippper character is highlighted, the info box on the right side of the screen states, "Do not fear the Ripper," an obvious allusion to the Blue Öyster Cult song, "(Don't Fear) The Reaper".
• The unlockable bonus track "Guitar Hero" is played by Monkey Steals The Peach, a fictional band comprised of rotating members of the Harmonix art team including Mike "Swid" Swidereck (Level Artist and Bassist), Ryan Lesser (Art Director and Guitarist), Daniel Sussman (Producer and Guitarist), and Jason Kendall (Art Associate Producer and Singer).

Guitar Hero: Rocks the 80s

• The clock around the neck of the character Grim Ripper shows the time near midnight, possibly as a reference to the popular 80's Iron Maiden song 2 Minutes to Midnight.

• After the encore at the Battle of The Bands, your drummer disappears in a puff of green smoke, yet another reference to the movie This is Spinal Tap.

• Some of the loading screens prior to a song are jokes and references specific to that song; for example, before encores, it tells the player never to "just jam" when the audience wants an encore (a reference to the movie This Is Spinal Tap), while prior to "Jordan", the player is told that wearing a bucket on one's head won't improve one's performance, a direct reference to the song's artist, Buckethead.
• The scrolling text on the walls of the school venue contains various lyrics to Alice Cooper's "School's Out".
• Clive Winston will use a violin bow to play his guitar when star power is activated with him.

Pandora also mimics this action sometimes when her star power is activated, yet she does not actually have a bow.
• Xavier Stone will sometimes pick his guitar with his teeth when using star power, a tribute to Jimi Hendrix.
• In Practice mode, the bedroom has many Rolling Stones references. A Their Satanic Majesties Request poster, Let It Bleed album, and a poster of the band themselves in the far right corner.
