Last night on Late Show With David Letterman, Slash stopped by to plug his new book and clear the air with Axl Rose, although maybe doing so by talking about how Axl kicked his grandma off her perch on the couch so he could crash out until mid-afternoon–and how Axl responded to being rebuked for his couch-ganking by jumping out of a moving car–wasn’t the best plan of action for doing so, given his, uh, temperament. Guess we’ll be seeing another Velvet Revolver album in the next few years!
