Does every song use this AC/DC anthem? See the "live":http://www.youtube.com/watch?v=tXaZmY52gHM video. But what does it mean? Of course there is a site "Lyricinterpretations.com":http://www.lyricinterpretations.com/lookat.php/bands/ACDC/bc5943285fcf975 that people speculate:
This song is dedicated to lead singer Bon Scott who died of asphyxiation, after choking on his own vomit in his friend's car after a night of drinking. May He Forever Rest In Peace!
The song is talking about how they rereleased some of Bon's Songs after he was dead.
I'm Back in Black (black is the color of death, so "I'm back from the dead")
I love the internet, some more surfing and you find Hells Bells on the "ukelele":http://www.youtube.com/watch?v=7_u8Gy7FwYg&feature=related, its actually pretty good:
