Lets play a game... winner gets 50,000 points!!?

Ok, 10 points. I have chosen a shared theme, common amongst the following: 'One' by Metallica.. 'Civil War' by Guns N Roses.. 'Knocking On Heaven's Door' GNR version. (Disregard the fact that 2 are by the same band.) So, there's something unique to all of these songs. First to guess right wins. I'm bored :p
