I believe it grew out of the terrace violence in the late 60's early seventies. I remember trouble in the Milton going back to the old fairs cup against Newcastle. There were anti pompey songs backin the early seventies (e.g. I love to go a wandering through the Milton rd, repeat, and if I see aPompey fan I'll kick him the head, and if see a Pompey fan I'll kick him till he's dead.). Fact is not much action between the clubs then. The match in 84 was tense to say the least and was as bad then as it is now, if not worse. It's a shame though, growing up as a kid I kept a scrap book of Football photos from the papers particulary the Echo and remember having a fondness for Pompey (players like Ray Hiron, Milkins, Jimmy Dickenson, George Ley all featured). My mates at the time all Saints but felt the same.
