It's from the Days Of Thunder version of the song, and it has Axl speaking in between the lines of the second verse.
Momma put my guns in the ground
It wasn?t their faultI can?t shoot them anymore
How were they even supposed to know?That cold black cloud is coming down
All things can be healed in timeFeels like I?m knockin on heaven?s door
What, what were they doing?Hope that helps...
