We get shit support acts here. By law there has to be an Australian support act, but sometimes the touring act brings another act with them.
When I saw Guns'n'Roses in 1992 there were 2 Australian bands - Pearls & Swine and Rose Tattoo, then Skid Row and GnR. Even when GnR toured last year, Rose Tattoo were again the support act, followed by Sebastian Bach then GnR.
Ozzy had Sevendust as his support.
Best support act I have seen was a band called Vanishing Point who opened for Iron Maiden earlier this year. They were an awesome band. As it turns out the singer in my brother's old band is good friends with them. Apparently they are trying to secure the opening spot for Joe Satriani's up-coming tour.
I've posted this before -
