The great Dutch hymn "We Gather Together" celebrates Dutch victory in a battle of the war of independence from Spain. The hymn was adopted by Americans because it resonated so much with their own circumstances. It's a very relevant song this year, too, as the war between freedom and tyranny continues. Here's my VC post on the song, including the full lyrics, from 2005. And here's a good version of the song, from YouTube.YouTube has plenty of other versions too, if you want to hear pure organ music, or a church performance in Spanish.
