A great composition by Gerry Dempsey, who plays on the guitar and is accompanied by Ian Jacks on the violin. They dedicated the piece to Israeli anti-nuclear whistleblower Mordechai Vanunu.
If you like the tune, make sure to also checkout this other version, which puts more emphasis on the violins, IMHO.
