Not in this lifetime...once in a lifetime
I had a feeling that when it was announced Axl Rose was giving AC/DC a dig out to finish their Rock or Bust tour, that I may not have the opportunity to see such a spectacle ever again. With Phil Rudd and Brian Johnson now apparently back in the fold for a rumoured farewell, it doesn't look likely that the world will get the chance to see Axl front AC/DC for the foreseeable future.
It's one of the greatest collaborations to ever happen in music. Hearing Axl sing that stuff in standard tuning was incredible. The man proved a lot of doubters wrong after pulling that off.
