Some interesting facts about this song...
1. It's GnR's only #1 on Billboard.
2. The guitar riff was just something Slash used for warm-ups.
3. Axl was supposed to keep singing at the end, but he didn't have anything. Thus, we get him repeating "Where do we go?" He apparently didn't know where to go next with the song.
BTW, the song also has one awesome guitar solo.
