Go “behind” Beyond the Thunder with this special bonus episode which wraps up Season 3 by answering listener letters while unearthing never-before-heard interviews with NASCAR driver and AC/DC super-fan Clint Bowyer, who joins the show to share his insights on the band's impact on the racing community, while Canadian heavy metal legends, Anvil, reminisce about meeting the original AC/DC lineup backstage, including a semi-sober Bon Scott. But that's not all – Australian children's entertainers, The Wiggles, also make a surprise appearance to discuss their unexpected love for the band, including an exclusive live performance of an AC/DC beloved classic from their big red car.
