Jarama Valley, the song inspired by one of the key battles of the Spanish Civil War, has been reworked and released on a CD to mark the 75th anniversary of the conflict.
Billy Bragg performs the famous song of the British Battalion, plus Maxine Peake delivers La Pasionaria's emotional farewell speech to the International Brigades with a dub backing from The Urban Roots.
Specially produced for the International Brigade Memorial Trust (IBMT), the artists have donated their talents for free and proceeds from the CD go towards the IBMT's work.
