Here are the titles of the songs and the limited comments on those songs:
"Old Man" from Gdan'sk The tune is traditional. The text is about the negotiations. "Pyk, pyk" means "puff, puff," as when smoking a pipe, and the name of the chief negotiator was Pyka.
Our Demands (Zsdania) There was enormous increase in poem-writing during the strike. This is one of those poems.
A Ballad from a Shipyard . (it's to the tune of The Times They Are a Changin')
Postulate 22 The striking workers made a list of 21 demands to the government. This is the 22nd demand, and the very prerequisite of the others. This poem became somewhat of a signature of the trade movement. It was set to several different melodies.
The Song of the Free Trade Unions An old Polish folk-song with a new text. There are many parallels to the old American trade union songs
