Following news that Daren Caperna of the Dallas, TX-based tribute band Back In Black was flown to Atlanta for an audition last month, Lee Robinson of Raleigh, NC-based Thunderstruck is now sharing details of his encounter with the group.

"I didn't sleep for like 3 days," explains Robinson after receiving the audition call. "I was studying the songs." On March 14, the singer hooked up with AC/DC at their Atlanta rehearsal studio and learned it was bassist Cliff Williams who discovered the Thunderstruck singer and suggested him as an option. "He hung with me the whole time," says Robinson. "Cliff found us on YouTube!"

Like Caperna, Robinson sang four songs before running through the full Rock Or Bust setlist, minus two songs. Once finished, guitarist Angus Young offered some words of encouragement to the singer.
