Looses all the production, mood and the most fucking epic solos played by Slash.
I fail to see the point of that "version" (the performance, not you posting it BTW).
The greatness in the original for me is the subtle layering which creates a massive pad throughout the song and allows the lead vocals and guitar to shine on it. I think this song is the fore- runner to my love for dark prog infused rock and metal.
Edit: don't mean to say the song is prog at all, but it is dark and builds and is heavy without being too complicated or in your face.
