He was a tell it like it is type and could be critically honest in his views of the sporting world. He demanded utmost participation and effort and his view of pro wrestling was no different. His column in the Star titled 'With Pick And Shovel' (and later as Sports Editor) frequently covered the sport and as a referee he had a unique perspective on the going ons in the squared circle.
Marsh was an early supporter of boxing promoter Jack Corcoran and his Queensbury Athletic Club who later got into pro wrestling before passing the office to the Tunney Brothers. Marsh and Corcoran ran in the same circles hunting and fishing together. They had both served as judges for amateur trials held across the county in the 1920's and Marsh frequently served as ref on Corcoran's boxing cards.
In May 1924 Marsh reported on a card held at Arena Gardens with a main of Stanislaus Zybysco vs Canadian heavyweight champion George Walker. Calling it as Toronto's first taste of 'big league wrestling' he described the then 53 year old Zybysco as having a 'stomach with a double chin effect.' and a 'rolly polly Pole with the bullet head,' and that the bout was like an 'acrobatic contest between an eel and a seal lion.' He summed up the prelim bout between Larry Ness (lightweight champ of New York) and Jim Watson (champ of Canada) as 'the bunk'. 'If either one is champion of anything I'm Carry Nation.'
After Ivan Mickailoff brought regular pro wrestling into Toronto, Marsh was a frequent critic of the participants. He could also be impressed so would assume he was 'smartened up' or maybe the style was just that convincing. Upon seeing Gus Sonnenberg defeat Dan Koloff in Oct 1929 he remarked 'Gotta give the wrestling champion (Sonnenberg) credit, boys. He certainly gave the lads and lassies who packed Andy Taylor's parlors to the roof plenty of action. What a sweet workman he is. Short squatty, with all his weight where he needs it most, he is as quick as a flash and he knows the game, a brainy, smart fellow.'
In 1930 after Corcoran's first pro wrestling card at Massey Hall Marsh weighed in on what he perceived as a double cross against the promoter. He stated that Corcoran was 'butting into the racket of well organized combine' and 'he might be dead lucky that the only thing that gets the ride is his pocketbook.' He implied that main eventer Jack McCarthy was 'pie-eyed' and that Corcoran would be 'well advised to stick to the boxing end of sports promotion.'
A couple of weeks later on the eve of Corcoran's second card featuring Jon Pesek Marsh opined that the first card which had been plagued by 'razzers' were in fact a 'paid clique' sent to disrupt the card on behalf of others (presumably rival promoter Ivan Mickailoff). He said it was openly charged that the hecklers were paid 25$ to start trouble at Corcoran's debut and that the same parties set up a pair of double crosses on the same show.
Pesek proved to be popular and even impressed Marsh who also suggested that Corcoran and Mickailoff get together and set up a Pesek-Sonnenberg (Sonnenberg appearing on Mickailoff cards) bout to 'pack them in.'
He retired as a referee several years later though he would occasionally come back for one-offs, some at the Bowmanville Lions Club. Corcoran had more than once offered Marsh as much as $500 to ref a bout in Toronto. it would have made for some publicity as Lou didn't like modern wrestling and the public knew it. Marsh always refused. Just a few weeks before Marsh passed away suddenly in 1936 he had reffed at a Corcoran charity show in Hamilton. Corcoran had asked and Marsh offered to do it only if Jack worked one bout as well, so they did.
In late April 1936 Marsh was having a bite at a cafeteria and suffered a cerebral hemorrhage. Initially they thought he would recover but on Mar 4 suffered a fatal stroke. Upon his death Corcoran related several anecdotes including crediting him with saving him when their canoe turned over on a fishing trip. He was said to have saved close to a dozen people from drowning over the years.
Marsh was so influential and respected the Star devoted all of its cover and most of its first 4 pages to him when he died.
They named an award after him to be awarded to Canada's top athlete each year starting the year of his death. No pro wrestler has ever won it but in 1953 Doug Hepburn won it for weightlifting. He had a brief tenure as a pro wrestler here in Toronto in 1955, we looked at him on the main site at Doug Hepburn: Worlds Strongest man
