Cool idea!

As a big time GNR fan, I hate the alt. version, but that final verse is definitely better than the "original"! So I would be very interested to hear the final product if someone's able to pull it off.

FYI, in case some people don't know it there are actually 3 versions of Don't Cry; with the first one being from 1987 with Adler on drums; which off course didn't make it on Appetite, because they didn't want any ballads on it.
