I prefer songs that everyone in the room, or on the street, can join in with. Most of the songs mentioned above only work in a quiet dsetting with everyone listening. They have too many words to be effective with a crowd or with people who don't already know them. Sing-a-longs also have the benefit of promoting feelings of fellowship and solidarity among the assemblage.

I few good ones of the sort I favor have been listed above, here is a list of some that I have been singing at recent demonstrations:

This Little Light of Mine (with lyrics like We've got the peace light burning . . .); Blowing In the Wind; We Shall Overcome (We shall live in peace . . ., We are not afraid . . .); Down By the Riverside; Hinei Ma Tov; Lo Yisa Goy; We Shall Not Be Moved (We'll work for peace and freedom, we shall not be moved); Paz y Libertad; and Last Night I Had the Strangest Dream.

I would love to see (or be reminded of) other songs of this type.
