The band consists of his two brothers: Ryan (his twin) and Ross (youngest sibling). Gary is the most political member of The Cribs, and can regularly be heard in interviews railing against inequality and misogyny in the music industry. This could be attributed to the fact that he spent a few years prior to the bands success participating as part of the committee that put on the UK's first "Ladyfest" in London, and also numerous fundraisers around this time.
His first job was working in a vet's practice, however he found the emotional strain too much, and soon realised that he was not destined to administer to animals for a living. His next job was working in a toilet paper and serviette factory where he claims that along with his brothers "We were the sole manufacturers of napkins in the UK.".
Gary is endorsed by Fender basses, of which he prefers the Precision and Mustang, and Ampeg bass amplifiers, using valve Classics and Vintage, as well as the solid-state SVT 350, through classic 8x10 cabinets.
