On their way into the Rock and Roll Hall of Fame, Guns N' Roses got together for one more gig. Axl Rose missed it. The hedonistic hard rockers, who became the world's top music act amid endless dysfunction, members of Guns N' Roses reunited for three songs on Saturday night before 6,000 fans, many of whom were thrilled to see at least most of the band's original lineup jam on classic hits like "Sweet Child O' Mine" and "Paradise City."
