Triple M will tell you they are. Very average band. Got a bit of success overseas and Australians are obbessed with Australian bands who have success overseas, even average music groups like Midnight Oil
Im guessing you werent around in 80 - 81 cruising around with your mates and cranking Head Injuries to ear-splitting, partying, surfing etc. having the time of your life. Or seen them live at their peak.
If you weren't or didnt, you dont know sh*t about the Oils.
