Prior to professional wrestling Kirk was a coal miner and professional rugby player. From 1954 he played 38 first team matches at prop forward (number 8) for Featherstone Rovers, scoring one try, 2 matches for Castleford and also for the struggling Doncaster club where he was a team mate of another future professional wrestler, Ted Heath.

After Big Daddy had delivered his signature Big Splash and scored the winning pinfall, Kirk turned an unhealthy colour, was rushed to the James Paget hospital in Gorleston and pronounced dead on arrival. The inquest into Kirk's death found that he had a pre-existing heart condition and cleared Crabtree of any responsibility.
