Protest song - it isn't nice

The song "It isn't nice" was one of the songs sung in the 1960s by civil rights marchers in the US, without whom Obama would not be able to even sit with the whites in a bus, let alone reside in the White House. The words and music was composed by Malvina Reynolds and was copyrighted in 1964 by Schroder Music Company, and was renewed in 1993. The Japanese version is banned in Japan. Here is part of the lyrics (for the full lyrics, refer to Malvina Reynolds: Song Lyrics and Poems:

It isnt nice to block the doorway
It isnt nice to go to jail
There are nicer ways to do it
But the nice ways have all failed
It isnt nice; it isnt nice
Youve told us once, youve told us twice
But if thats freedoms price
We dont mind ...
