Giant Haystacks was perhaps one of the biggest men to ever step into the 'squared-circle' of professional wrestling, He stood 6' 11" tall and at his heaviest tipped the scales at just over 49 stones (around 686lbs). In the confines of the ring, Haystacks was a consummate villain who berated both the fans and the babyface wrestlers while using his overwhelming bulk to flatten the opposition. He started his wrestling career in the late 60's under the name of Luke McMasters but that was soon changed to Haystacks Calhoun and finally Giant Haystacks. He worked for Brian Dixon's Wrestling Enterprises for several years before moving over to Joint Promotions in 1975. 

He made his television debut that year partnering the villainous (at that time) Big Daddy against the popular team of Roy and Tony St Clair. He was a sensation right from the first bell and enjoyed top of the bill status thereafter. Before long he turned on his partner Big Daddy who had now seen the error of his ways and he also feuded with Kendo Nagasaki for a time. During his career he wrestled all over the world but always enjoyed his Irish tours the most. Although born in London, he came from an family of giants from the west of Ireland. His real name was Martin Ruane and his parents hailed from Brickens near Kiltimagh in County Mayo and cousins and uncles and aunts always came to see him whenever he was wrestling in that area.

He also enjoyed his trips to Canada to wrestle for Stampede Wrestling. In Canada he was billed as The Lough Ness Monster and was managed by John Foley who had been a member of The Black Diamonds tag team in British rings with Abe Ginsberg. As the Lough Ness Monster he also worked for World Championship Wrestling in the United States. When he was in good form 'Stacks was great company and had lots of stories to tell about his exploits. But half the time he was making them up as he went along. You couldn't really believe anything he told you. He was a spoofer. He appeared in the Paul McCartney movie Give My Regards To Broad Street and at the wrap party Paul gave him a guitar which he treasured. He said that he could play it but with those enormous fingers I'm not so sure. Martin's big ambition was to host a chat show on television. But unfortunately it was not to be. He was diagnosed with cancer in 1996 and died two years later aged 52.
