chokes replied to NeonKinight's topic in GUNS N' ROSES - DISCUSSION & NEWSI don't think it was necessarily anything specific Slash said. After the breakup Slash had a go at Axl in every interview and appearance whereas Axl disappeared for almost a decade. Axl saw that as a betrayal.
Axl and Slash are 2 of the most recognizable musicians in history, they don't need any introduction. I'm sure the one time Axl did it at the start of the tour was just out of courtesy, a way of saying Slash is back in the band.
