I don't think it's as simple as that they trod the boards in the states for quite awhile before H2H it was a build, Cold Chisel for example were the complete opposite they had no appetite to put the work in & gave up after 3 weeks.Not disagreeing with any of that.
The entire point of Highway to Hell - Back in Black was to refine the sound to break them in the US.
It worked. No matter what anyone thinks of it, it worked.
