It's never easy to replace a founding member of a band who dies tragically, but AC/DC's Brian Johnson fit in with the Australian hard rocking band perfectly, and was accepted immediately by the group's legion of fans. Born on October 5, 1947, in Newcastle Upon Tyne, England, Johnson sang with a church choir as a youngster, but like zillions of other teenagers of the '60s, was taken by rock & roll. In early 1972, Johnson formed his first serious rock band, USA. Just a few months later, the band changed their name to Geordie and focused on hitting it big in the then-thriving U.K. glam rock scene. The band scored several hits in their homeland, including the Top Ten "All Because of You" and the Top 20 "Can You Do It."
