You have just confused two games 11 months apart.
October 1988 we beat Plymouth away 6-3 in the League Cup.
The game was scheduled for the Tuesday but I was on the supporters club coach traveling down to the game and it got called off when we reached Taunton due to torrential rain.
Couldn’t make the game played the next day when we won as above.
I was then on the coach to Plymouth again for the 2nd Division game 3 days later, on the Saturday. And we had been away at Ipswich the previous Saturday!
