"Back in Black" is a song by AC/DC, appearing as the first track on side two of their 1980 album of the same name. Known for its opening guitar riff, the song was AC/DC's tribute to their former singer Bon Scott. His replacement Brian Johnson recalled to Mojo magazine in 2009 that when the band asked him to write a lyric for this song, "they said, 'it can't be morbid - it has to be for Bon and it has to be a celebration.'"
