Been over here since '82, so only sporadic attendance since then. Therefore, of the matches I actually attended, 2 or 3 stick in my mind.
1. Nov '75, City 4 Scum 0, League cup Rd 4. The game that Colin Bell was injured by that koont Martin Buchan
2. April '81, City 1 Ipswich 0 F.A. Cup s/f. Probably the best atmosphere at an 'away' game (neutral ground, so neither home or away, but you know what I mean!) that I've been to. Villa Pk was alive with blues that day; I was in the Holte End, bang in line when that Paul Power free kick went in. Thought I'd died and gone to heaven after the game. Enjoyed it far more than the final, TBH.
3. Sept '81, City 3 St(J)oke 1 Division 1. Tricky Trev's (the original) debut. Glorious sunny day, The Victoria ground was packed with blues and TF scored twice on his debut. Phil Boyer scored the other, IIRC.
