"Headbanger" Harris was a member of the crew of Red Dwarf before the accident which killed the crew. Although unseen, Harris is mentioned as being the kitchen porter, so it was likely he was working in the galley alongside chefs Tim, Olaf Petersen, and Selby and Chen. Headbanger Harris was an avid drug user and Dave Lister once acquired (i.e. stole from his locker) a consignment of Titan Mushrooms, also known as Freaky Fungus, from Harris. Lister used some of these to cook a breakfast for his bunkmate Arnold Rimmer, rather than snitch out Harris to Captain Hollister. ("Stasis Leak")
