It could have been a recipe for disaster ... but when former boy-bander Joey Fatone grabbed the mic at a bar this weekend and busted out some Guns N' Roses -- dude blew everyone away.
It all went down at the Dubliner Irish Pub at Mohegan Sun Casino in Connecticut this past weekend -- when Fatone went on stage with local band "Red Light" and channeled his inner Axl for "Sweet Child O' Mine."
Not too shabby.
