Martin Austin Ruane (10 October 1946 – 29 November 1998)[5] was a British professional wrestler of Irish parentage, best known by the ring name Giant Haystacks.

After Big Daddy turned face and the team broke up, the two engaged in a long-running, high drawing feud.

[5][7][11] Ruane began wrestling in 1967, initially for the independent WFGB as "Luke McMasters" (later incorrectly reported as being his legal name).

[5] Haystacks' TV debut came in July that year, when he and Daddy teamed up against the brothers Roy and Tony St. Clair, losing by disqualification.

[14] Subsequent televised tag matches at Christmas that year and through 1978 would mostly result in Haystacks abandoning his partner to concede the losing falls to Daddy[14][15] (although on one occasion in August 1978 Haystacks would return to knock out Daddy's tag partner Gary Wensor for a rare 2-1 victory.

[5] Meanwhile, on 23 November 1978 at the Royal Albert Hall, Haystacks captured the British Heavyweight Championship from Tony St. Clair by splashing St.Clair in the knees to win by a technical knockout.

At this point manager Lloyd Ryan and Nagasaki impersonator King Kendo took over the feud, lasting until Haystacks's 1996 WCW debut.

He also worked for the CWA in Germany and Austria, winning several trophy tournaments there, as well as in India,[10] South Africa where he feuded with local fan favourite Jan Wilkins and Zimbabwe, where he was made an honorary citizen.

[11] In January 1996, after spending time as a debt-collector in Manchester, selling cars, and undergoing knee surgery,[5] Ruane debuted in the United States for World Championship Wrestling, under the ring name "Loch Ness".

[7][11][24] In 1990, he also appeared on S4C in an episode of the Welsh language soap opera Pobol y Cwm, as himself when he came to the valley for a wrestling match with El Bandito (Orig Williams).

[26] A play by Brian Mitchell and Joseph Nixon, Big Daddy vs Giant Haystacks, was performed at the Brighton Festival Fringe between 26 and 28 May 2011.

[27][10] Manic Street Preachers mention Giant Haystacks in their song "Me and Stephen Hawking" from their ninth studio album Journal for Plague Lovers (2009).
