The Unthanks: "Lullaby for Hamza"

I seem to have missed this version of Robert Wyatt and Alfreda Benge's "Lullaby for Hamza" by The Unthanks (found it over at Hibou, Anemone & Bear today). It was performed for The Lullaby Project at the Howard Assembly Room in Leeds (more videos here). The original song is on "Cuckooland" (Domino 2003).
