John Morrissey (February 12, 1831 – May 1, 1878), also known as Old Smoke, was an Irish American bare-knuckle boxer and a Dead Rabbits gang criminal leader in New York City in the 1850s and later became a Democratic State Senator and U.S. Congressman from New York, backed by Tammany Hall.
 Morrissey began his bare-knuckle boxing career after a confrontation with a man known only as "Chroel" who was notorious for troubling his fellow townsmen.
 Although Morrissey was on the bitter end of his first bare knuckle bout, his display of bravery and fortitude earned himself the respect and historical acknowledgment of his peers.
"Big Strong Man" or "My Brother Sylveste" is an English-language folk song, commonly associated with Ireland and performed by Irish bands.
 It's not known when the song was originally written, but the date might be reflected in the references to the "Jeffries-Johnson fight" of 1910, American boxer Jack Dempsey, who started boxing in 1914, and to the RMS Lusitania which was in service from 1907 to 1915.
 It's also not known who wrote it, or even if it came from Ireland or another country, but having "lived in a caravan" might indicate the main character is from the Irish Traveller community – a community renowned for its boxers, both bare knuckle and professional.
 The song was popular with Canadian soldiers in World War II.
The Bare Knuckle Boxing Hall of Fame is a museum and hall of fame in Belfast, New York, dedicated to the sport of bare-knuckle boxing.
 It is housed in barns that were once owned by the Greco-Roman wrestling champion and physical culture pioneer William Muldoon.
 The heavyweight boxing champion John L. Sullivan, who fought in both bare-knuckled and gloved boxing contests, trained in these barns under Muldoon's guidance for his championship bout against Jake Kilrain in 1889.
 The barns were originally across Main Street from their current location, on the grounds of the Belfast United Methodist Church.
 They were bought, moved, and restored by Scott Burt when the church became no longer interested in maintaining them.
 Burt opened the Hall of Fame in 2009, when it had its first induction class.
