The band releases the single, The Jack, from their album, T.N.T. The song is about a venereal disease. “The Jack” is the Australian slang for gonorrhea. Scott:
We were living with this houseful of ladies who were all very friendly and everyone in the band had got the jack. So we wrote this song and the first time we did it on stage they were all in the front row with no idea what was goin’ to happen. When it came to repeatin’ ‘She’s got the jack’ I pointed at them one after another.
