Oddessy No. 5 is still my favourite album of theirs.
I'm no music buff lol but IMO it's harder for modern bands especially Aussie bands to get the wider Aussie public recognition than in past generations where music outlets were limited to say pubs, 3XY lol and Countdown. There are no longer any prime time tv shows devoted to the latest music both Aussie and OS. So whereas AC/DC, Midnight Oil, INXS, Cold Chisel, etc were beamed into nearly every home, you now need to make it big OS or tell your life story in New Idea lol before the wider public take notice of you. I would say most people would know about Kylie say than any other Aussie act.
I have a mate who knew those in Jet before they hit the big time. He would agree with you Jake about the tosser bit lol.
