Protest songs from around the world

It's Friday! To give our picketers a bit of inspiration (and inspired in turn by the great teach out at the Institute of Education), we're happy to present a series of protest songs and songs about social justice from around the world. Can you spot the theme?

Barricades (Yiddish)

The Victory of the Cloak-makers (Yiddish)

Nunarput utoqqarsuanngoravit (Greenlandic national anthem)

Still Here (Welsh)

And instead of a protest song in Kîîtharaka (a free pint to the first person to post one!) we offer a song in Quebec French, the focus of some discussion at Strike School:

Half-Mast (Quebec French)

We can't promise we'll have them memorised by Monday, but we'll be very impressed if you do. Think we've missed one? Add it in the comments below, or tweet us at @CHonStrike!
