"“The Jack” originally featured on the 1975 Australian release of T.N.T. and the international release of High Voltage the following year. The title is a reference to gonorrhea. “We were living with this houseful of ladies who were all very friendly and everyone in the band had got the jack,” Scott told Sounds in 1976, according to SongFacts.com. “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.” Angus Young added, “After that, wherever we did the song the girls in the audience would run to the back of the hall.” "
