• An early AC/DC track, this one plays off their band name, keeping with the electricity theme as Bon Scott sings about their "high voltage rock and roll." The band would produce many more songs about rock and roll over the next four decades, and these tracks were often the showstoppers at their concerts.
• AC/DC's first album, released in 1975 only in Australia, was called High Voltage, but this song wasn't part of it. "High Voltage" the song was released as a standalone single, reaching #6 in Australia and goosing sales of the album.
  
  Another Australia-only album (T.N.T.) followed later that year, and in 1976 tracks from these first two albums were compiled, along with this song, for another album called High Voltage that was given international release and set the stage for the band's rise to stardom. The "High Voltage" single was also released internationally in 1976, and a video was made to promote the song.
• This was the first AC/DC song on which drummer Phil Rudd played.
