AC/DC has unquestionably written some of hard rock's greatest and most enduring anthems of all time. While such hard rockers as "Back in Black," "Highway to Hell," "Dirty Deeds Done Dirt Cheap," "Sin City," "T.N.T.," "Let There Be Rock," and "Who Made Who" come immediately to mind, one of their finest would have to the title track from their 1981 album, For Those About to Rock (We Salute You). Since its initial release, the song became a bombastic concert-closer for the band -- complete with rallying-cry chorus and the blasting of stage prop "canons." In England's Kerrang magazine (reprinted in Mark Putterford's AC/DC bio Shock to the System), guitarist Angus Young explained the origins of the song around the time of the album's release -- "We had this chorus riff, and we thought, 'Well, this sounds rather deadly.' We were trying to find a good title...and there's this book from years ago about Roman gladiators called For Those About to Die We Salute You. So we thought, 'for those about to rock.' It's a very inspiring song. It makes you feel a bit powerful, and I think that's what rock n' roll is all about."
