Trivia

 * This is the first song that was ever sung in the series.
 * At the start of the intro version of the song, the Crystal Gems' gems glow.
 * In the main series, the song was sung by all of the Crystal Gems, while only Steven sang the song in the Pilot.
 * The melody of this song has been sampled in several of other tracks, such as Steven's Shield and Fight, Flight, or Love.
 * Starting with "Sworn to the Sword", the intro has been changed; the song is more upbeat, the scenes are different, and the Gems are in their post-regeneration forms.
 * In the new intro, Connie can be seen with Rose's Sword, Jamie can be seen sitting on a beach, Onion can be seen on the roof of the Big Donut, and the town seems more lively in general.
 * Greg is seen laying on Lion playing an electric guitar, which is the same guitar he plays in We Need To Talk and Story For Steven.
 * Steven and the Crystal Gems can be seen on a Warp Pad in space, with Earth and the Moon in the background.
 * At the Adventure Time/Steven Universe panel at San Diego Comic Con 2015, more of the songs lyrics were released in a video featuring a young Steven singing, as well as other Crystal Gems.
 * It follows a similar pattern the the extended opening from the pilot for the first scene, such as Garnet and the rest of the gems clapping along to Steven playing the song on his ukulele.
 * It also revealed that the song was written, as far as in-universe canon goes, by a young Steven just having learned to play the ukulele prior to making the move from his dad's to moving in with the Crystal Gems.
 * An earlier form of Amethyst is seen earlier in the video when Steven was young. She wears a purple sweater similar to the one seen in the Pilot. After the house was completed, Amethyst is seen in her debut form in a purple tank.
 * The video pays homage to the original opening where the gems are running as Steven catches up, runs in front of them and jumps.
 * On the video presented, a shadow of an unknown gem can be seen alongside Homeworld gems Peridot, Jasper and Lapis Lazuli. The gem is speculated to be Yellow Diamond.
 * In the extended version sung on the San Diego Comic Con 2015, a montage of various clips from previous episodes were shown as Steven and the Crystal Gems run along the beach, reminiscent of the first opening sequence. These clips include (in order of appearance):
 * "Gem Glow"
 * "Bubble Buddies"
 * "Lion 2: The Movie"
 * "Ocean Gem"
 * "Lion 3: Straight to Video"
 * "Alone Together"
 * "The Return"
 * "Jail Break"
 * The extended version shown at the Adventure Time/Steven Universe panel is the first time any homeworld gems are shown in the theme or intro
