Truly one of the greatest still-living guitarists in Rock, Billy Gibbons of ZZ Top was pelted with debris in Australia by a pissed off audience!  Depending on which side you believe here, Billy apparently was promoted incorrectly, he was touring Australia to talk about hot-rods and custom cars. and play an occasional song. The people who bought tickets to his shows thought he was going to play ZZ Top songs all nite! After just 3 shows, Billy cancelled the tour in Australia and got the hell out of Dodge!
