Preston - Villa on the opening day of 72/73 was at Deepdale

I thought Gregory had departed before then. He started the 71/72 season as captain after Godfrey had left for Bristol, but soon fell out of favour after bitch slapping our goalie (Tommy Hughes?) in a league cup game at Wexham. There were rumours that the players refused to come out in the second half if he was in the team.
I can remember him scoring with a half volley from the edge of the area in an Easter game in 71, which may have been either Wrexham or Swansea, but can't for the life of me remember his other goal. Maybe Doncaster away.
