I remember that game - we were near the back on the open end (Clock End ?)
When we conceded early I thought we could be heavily beaten. My recollection is we held on with a mix of good luck, some good goalkeeping and then Billy Tucker headed in from a corner in th a last 5 minutes.
Brilliant night!
Maybe my memory has rose-tinted glasses. I was at Highbury too, I seem to remember Arsenal not threatening our goal so much after the early penalty.
"We all went, we all saw, Billy Tucker force a draw, la la la la, la la la, la la... repeat :-)
