Somebody has probably already mentioned these, but
The 1969 ? 6-0 win over Torquay on Boxing Day with Mike Bickle getting 4,
The 1969 2 -1 win over Swindon the week after they'd beaten Arsenal in the league cup final. Argyle formed a guard of honour for Swindon as they came onto the field, who I believe had the cup displayed on the pitch. Clearly recall Bickle scoring after being set up from an indirect free-kick on the 6 yard line with the entire Swindon team squashed along the goal line. Please bring back the indirect free-kick!
The 3 - 1 win over Torquay with Hughie Reed tearing them apart and then scoring with a flying header (despite being the shortest player in the league)
The 1975 4 - 3 Boxing Day win over Swindon after being 1 - 3 down in the Waiters promotion year.
The 3 -1 play-off win over Colchester when Williams scored in the last minute was fantastic.
The 4 - 4 New Years Day Kevin Hodges-inspired draw with Cardiff in torrential rain after we were 2 - 4 down. That was the Dave Smith promotion year.
The 2 - 0 win over QPR to clinch the title.
I shall stop there before I think of 6 more!
