I was at this one mate. Got on the bus from the Red Hackle on the Scotch estate and we played music and talked football all the way to Wembley whilst imbibing far too many beers. We got off the bus and it was like a huge party atmosphere, we went to a nearby pub then had a walk around ready for kick off, randomly bumped into a few friends and then we were in the ground. my strongest memory is from half time, went for a pint and it was like a carnival atmosphere under the stands with fans just singing and celebrating and TBH I cannot remember a more positive atmosphere at a Sunderland game there was just something in the air that day.
Not sure if this will be any good but I'll stick it in here anyway https://www.bbc.com/news/articles/c0w4k4741xqo
