The 1980 rock classic Axl Rose admits is “really challenging” to singEvery vocalist, whether it’s Axl Rose or Liam Gallagher, would drop everything at a moment’s notice if their favourite band came calling. However, frontman Brian Johnson had to leave the band due to a sudden bout of hearing loss, which could have been permanent if he had played another show without getting treated. Initially, they postponed the shows, before Rose heard the news, volunteered, and AC/DC hit the road. As the temporary AC/DC frontman, he tried his best and, more often than not, reached similar levels that Johnson could. While Johnson was irreplaceable, Rose, who is far better suited to Guns N’ Roses, did as well as anybody possibly could.
