No idea what The Conqueror is but Rose Tattoo were a notorious Australian pub band. The lead singer "Angry" Anderson is now notorious for his involvement in conservative politics and appearing on trashy tabloid current affairs shows. Oh, and he is also infamous for this dreadful performance at a football grand final. Note the black guy at 2:52.
BTW, Rose Tatto's drummer is in big trouble for being a weapons smuggler: http://www.abc.net.a...ly-ring/5358986
