I went to see a little-known band called "AC-DC" in 1975, which I really enjoyed. 30 years later I really enjoyed a bluegrass band called "Hayseed Dixie" singing the same old songs, but arguably, better! Cheers, Terry. 
AC-DC I think I may have heard of them, Aussie style country & western band weren't they 
I saw another one of your little Aussie bands once, who were reasonably good. They played a one off gig called SummerXS at a little backstreet venue in London called Wembley Stadium 
Ha ha, well they were really a little known band when I saw them Crispy, at that stage they hadn't had a chart hit, and were still very rough, Bon Scott was blind drunk, or stoned, or both, and they were playing in a little country pub, to probably 30 people. I went "AWOL" from boarding school (for my sins, I'd been expelled from my previous school) to go to this concert, and it was a while later before "Long Way to the Top" became a hit.
By contrast, "Hayseed Dixie" was a very professional outfit, and I watched in awe as the lead singer drank about 20 Aussie beers (arguably the most potent brew in the free world) as he sang all the AC-DC hits, which seemed to have no effect at all on his performance! Of course, he'd be at least twice the size of Bon, he was almost bigger than me, ha ha! Cheers, Terry.
