This week, Jason and Dave welcome onboard a man who is absolute rock 'n' roll royalty! As the lead singer of AC/DC, Brian Johnson is a musical legend, but he's also a dyed in the wool petrolhead who has lived and breathed cars all his life! Talking to the boys from his home in Florida, Brian describes how the love affair with cars first started, and talks about some of the precious metal he's acquired over the years!
