Mark "Barney" Greenway (born 13 July 1969 in Great Barr, Birmingham) is a English extreme metal singer, who has been a member of Napalm Death, Extreme Noise Terror, and Benediction. Greenway has stated his nickname "Barney" came from a time when he used to drink alcohol. He stated he would get so drunk that when he went anywhere, he would bump into everything. From this behaviour, he would be called "Rubble", which changed to "Barney Rubble" and then just "Barney".
