The intro seems to be based on U2's 'Pride (In the Name of Love)'. In 2016, there was a guitar version of the song exclusive to the Sonic Runners Werehog event, which featured an electric guitar substituting the melody. It is also an unlockable track in Sonic Generations. A short, instrumental mix of this song, ' Knight of the Wind' and ' Sonic Heroes' appear in the Nintendo DS version of Mario & Sonic at the Olympic Winter Games for the Ultimate Figure Skating event.
An orchestrated version is composed by sound director Tomoya Ohtani for the Perfect Dark Gaia boss battle in Sonic Unleashed.
