The song is so bad (and the lyrics even worse) that it's credited to Pittman and Dizzy although Axl himself said that he's 'alone lyrically'. But assuming he's done something as bad as Silkworms would be heresy.
The music to it is amazing. Someone that saw it live at HOB said it sounded great and you miss a lot of the boot. Also I think the lyrics are good. They are better than anything goes.
