An explosive play called Bad Blood Blues, exposing the ethics of HIV drug trials in Africa, is to be performed in Sheffield at the beginning of March at Theatre Delicatessen on Eyre Street. The play by Paul Sirett explores the moral maze of drug trials on the African population by western pharmaceutical companies. It will be only the second time it has been staged in the UK and will mark the directing debut of Sheffield-based actor John Rwoth-Omack. Azz Mohammed reports for Sheffield Live!
