Happy 70th birthday to Brian Johnson of AC/DC who was born on 10/5/47. Johnson joined AC/DC in 1980, after the death of Bon Scott and recorded the blockbuster LP Back in Black. Johnson lead AC/DC through their most commercially successful periods up through 2016 when he had to bow out from touring due to hearing issues: Johnson was replaced by Axl Rose to finish out the tour. Johnson has since made some more live appearances with other artists, as we await his next lead singing chapter. Watch Johnson and AC/DC perform “For Those About To Rock We Salute You” live in 1981..
