Not a SB party story, but a good yarn nonetheless.
I was getting ready to leave for a semester studying in Madrid in Jan 1986. I was still in the USA for the Jets playoff game, and actually saw it in person thanks to my uncle, a Jets season ticket holder. I watched the Raiders game at home in RI, then took off for Madrid a couple days later. In those days, there was no way to watch the NFL on TV in Spain, but I listened to the win over the Dolphins in the AFCCG on Armed Forces Radio.
I was living with 3 other American college kids, including 2 Pats fans from RI and Mass. We desperately wanted to watch the Super Bowl ("When are the Pats ever going to make it again in our lifetimes???"), but it was impossible to watch outside of England. We tried to figure out a way to get on a US military base but no dice. So literally about 4-5 hours before kickoff we make the decision to fly to London to watch it at a bar catering to US students. Subway to Barajas, flight to Heathrow, tube to the bar. We get there and it was 3-0 Pats (woo hoo, upset baby!!) and I swear I turned around to get a beer and it was 46-3. Crashed with friends of friends studying in London and back to Madrid the next day. I don't think we did one single thing in London other than watch the game, sleep it off, then go back.
Ah, youth.
