I happened to come across this song by Pete Seeger. The lyrics seem to resonate with your gathering. Phil Ochs covered it too, and while I prefer Pete Seeger’s singing, Phil Ochs added this last verse that I think speaks to our times:
Only as strong as our love for this land
Only as tall as we stand
But our land is still troubled by men who have to hate
They twist away our freedom & they twist away our fate
Fear is their weapon and treason is their cry
We can stop them if we try.
