That's true - here's a rousing version from Shay Black in California. And particularly notable for the grand quote from James Connolly up on the wall in the background, which I'll transcribe here, so I know where to find it again:

No revolutionary movement is complete without its poetic expression. If such a movement has caught hold of the imagination of the masses they will seek a vent in song for the aspirations, fears and hopes, the loves and hatreds engendered by the struggle. Until the movement is marked by the joyous, defiant singing of revolutionary songs it lacks one of the most distinctive marks of a popular revolutionary movement; it is the dogma of the few and not the faith of the multitude. (James Connolly 1907)
