Music video description
Mr. Zoob is a Polish band that played mainly alternative rock. Around 1985 they recorded a song called "Kartka dla Waldka," in which the musicians mocked the band's friend, poet and lyricist Waldemar Chylinski. The first stanza of the song is a travesty of lyrics from Chylinski's poem titled The Gray Blues. The poet himself heard the song on television, got upset because he thought it was a plagiarism of his work, and then heard the refrain
Don't be angry, Waldek, this "streetcar" is really yours, and the rest is mine!
