Yes, you have already reacted to songs from the Woodstock festival, just to clarify, it is an annual festival attended by 500-550,000 people every year. There were over 750,000 people at the SABATON concert in 2012. It was one of their biggest concerts to date. I suggest you watch the 40:1 track from the same Woodstock in 2012.
This specific vid of Uprising by Sabaton was the begining of my 5 years now journey with this amazing band! I love all their songs. The more you listen the more you love them :-) Thanks for reacting to Sabaton and keep doing it! There are some more songs connected to Poland.
