Even though we sunk lower, i think some of the days in division 1 in the 1980s were pretty low - i remember lots of games at Firhill where we were terrible, crowds were low, and the team / manager were getting pelters for most of the game. A 0-3 v Forfar wasn't good but there were many.
Possibly the worst was a 5-1 defeat at Broomfield - Billy Lamint brought the players back put onto the park afterwards to shout at them in front of an enraged Thistle support. A very cowardly act, and i think he was sacked soon after.
The 7-3 home defeat by Saints was so bizarre as to be less bad somehow. Plus Donnolly scored a 25 yard back heel volley.
