Guns N’ Roses toured as Aerosmith’s opening act in the summer of 1988. It was a thrill for the band, since they all idolized Aerosmith and particularly Steven Tyler, and the two bands got along great. At first, a system was put in place to keep the bands separated, since Aerosmith had been through rehab and their management didn’t want them around drugs and alcohol. As the tour progressed, a mentor relationship formed between the bands, as Aerosmith saw their younger selves in Guns N’ Roses.
