After listening to Crash Diet several times I've come to the conclusion that it would be cool (though I know it will NEVEr happen) if the new GNR wre to do a remake of it.
Because this isnt your typical GNR song,its much heavyer sounding,and the solo is less finesse and more just raw agression.(perfect for Buckethead)
The only problem I see is the main chords a little 80's ish.
But I think that could be overcome.
Just a thought.
