Depends on when ln the 70s you started going.
Pre segregation ,which must have been 1974 ish, I can recall Pompey,Villa,Cardiff,Brizzle city fans and god forbid even the scum being in the Town end
Mind you , Swindon skins took the East end at Trashton gate in 1970
Since 1975 and never missed a derby.
Therefore by my reckoning Eric must be at least in his 50's?
Married, girlfriend, kids or what? ........
