Thanks to keberoxu for the note about the Berlin exhibition in honour of Wolf Biermann. There is a very good article in the Guardian today (11 July 2023) about the exhibition, and about Biermann's life and his songs. I love the quote from Gabriele Stotzer "His words and music went straight to the gut and we learned the songs by heart."

A lot of his songs are available on YouTube, but the 1977 Pluto Press English translation of his songs Ballads and Songs is long out of print.
