There's been some cracking atmospheres at non-Villa games too.
Lazio fans were loud in the Holte v Majorca in 99. Very colourful ocassion.
Scotland v Holland and Holland v Switzerland at Euro 96.
Liverpool v West Ham League cup final replay,
All those FA cup semis - Man Utd v Leeds in a night match in 1970 was the first I went to and the ground had a real buzz that night. I also went to a few semis where it was very quiet as well, probably as the games were often let downs.
