I said it before - that means nothing. GnR were opening for Iron Maiden and Axl was trashing them whenever he could. Van Halen was opening for Bon Jovi but other than Sammy Hagar, no one had a nice thing to say about Jovi. That's how it goes with opening bands. Slash only did a handful of gigs, mostly festivals - not liking Jovi doesn't make him a hypocrite .

Also, Slash and Richie played together before. Apparently Slash even persuaded Richie to give back some of the money to Skid Row ages ago...so I doubt he'd have a problem playing on Richie's record despite of the things he's said but I think he's heavily touring at the moment....
