The 18 stone prop is the nephew of the legendary professional wrestler Shirley "Big Daddy" Crabtree, himself a former rugby league player who played for Bradford Northern, although he never made an appearance for the first team.
The band point out in the album sleeve notes that this is in reference to the chant used by fans of the wrestler Big Daddy.
