This page shows the results of the Men's Wrestling Competition at the 1991 Pan American Games, held from August 2 to August 18, 1991, in Havana, Cuba.
 The Greco-Roman category was notable as it featured a gold medal performance by Randy Couture, who would later become a multi-time world champion in the UFC.
 The event also featured a gold medal performance by Mark Coleman, who would later become the first UFC Heavyweight champion.
"No Reply" is a song by the English rock band the Beatles from their 1964 album "Beatles for Sale".
 In North America, it was issued on Capitol Records' variant on the British release, "Beatles '65".
 The song was written mainly by John Lennon and credited to Lennon–McCartney.
 Lennon originally gave the song to another artist managed by Brian Epstein, Tommy Quickly, in June 1964, but Quickly decided not to use it.
 The Beatles recorded the track in London soon after returning from their first full tour of the United States.
 The lyrics typify Lennon's more introspective and mature songwriting on the "Beatles for Sale" album.
Wicked Lester was a New York-based rock and roll band that would later become known as Kiss.
 The band formed in 1970, under the name Rainbow.
 Two notable members were bassist Gene Klein (born Chaim Witz) and rhythm guitarist Stanley Eisen, who later adopted the stage names Gene Simmons and Paul Stanley, respectively.
 In 1971 the band changed their name to Wicked Lester, and recorded an album for Epic Records, which was never officially released.
Arzawa in the second half of the 2nd millennium BC (roughly from late 15th century BC until the beginning of the 12th century BC) was the name of a region and a political entity (a "kingdom" or a federation of local powers) in Western Anatolia.
 The core of Arzawa is believed to have been located along the Kestros River (Küçük Menderes), with its capital at Apasa, later known as Ephesus.
 When the Hittites conquered Arzawa it was divided into three Hittite provinces: a southern province called Mira along the Maeander River, which would later become known as Caria; a northern province called the Seha River Land, along the Gediz River, which would later become known as Lydia; and an eastern province called Hapalla.
William Gwynn (1856 - 1 April 1897) was a Welsh international rugby union forward who played club rugby for Swansea and would later become secretary of the Welsh Rugby Union.
 Gwynn was an all-round sportsman and as well as his success on the rugby pitch he also player cricket for Swansea, of which he became vice-president, and Glamorgan.
 Gwynn had also played association football and had captained Battersea College XI through two undefeated seasons.
 He would later become a referee and would officiate the very first football game between Swansea Town and Cardiff City.
Jeff Killed John is the last EP by Welsh nu metal band Jeff Killed John, before changing their name to Bullet for My Valentine.
 This EP also marks the last recorded material with bassist Nick Crandle, before Jason James replaced him.
 Many song elements from this EP would be reworked into later tracks for Bullet for My Valentine music: "Routine Unhappiness" contains riff elements that would later become "Tears Don't Fall," with lyrical content that would appear on "10 Years Today;" "Nation2Nation" would eventually become the bonus track "Turn to Despair" on the Japanese edition of "Hand of Blood;" and "All These Things I Hate (Revolve Around Me)" is an early demo of the song of the same name that would eventually appear on Bullet for My Valentine's debut album "The Poison."
Mexican professional wrestling promotion Empresa Mexicana de Lucha Libre (EMLL) commemorated their 15th anniversary with two "'EMLL 15th Anniversary Shows".
 The first Anniversary show was held on September 22, 1948 in Arena Coliseo in Mexico City, Mexico, EMLL's main venue.
 The second event took place two days later on September 24, 1948 in Arena Modelo.
 The events commemorated the 15th anniversary of EMLL, which would later become the oldest professional wrestling promotion in the world.
 The Anniversary show is EMLL's biggest show of the year, their Super Bowl event.
 The first anniversary show featured the EMLL debut of Blue Demon, who would later become one of the iconic figures of Mexican wrestling.
"Baby, You're a Rich Man" is a song by the English rock band the Beatles.
 It was written by John Lennon and Paul McCartney, and released as the B-side of the band's "All You Need Is Love" single in July 1967.
 The song was recorded and mixed at Olympic Sound Studios in London, making it the first of the Beatles' EMI recordings to be entirely created away from EMI Studios.
 The track features a monophonic keyboard instrument known as a clavioline, which Lennon played on its oboe setting, creating a sound that suggests an Indian shehnai.
 In its lyrical themes, the song addresses the "beautiful people" of the 1960s hippie movement and partly echoes the utopian message of "All You Need Is Love".
 The lyrics have also invited interpretation as a message to the Beatles' manager, Brian Epstein.
Christopher Nigel Walley (born 30 June 1941) is a former golfer and tea-chest bass player of The Quarrymen, which included John Lennon.
 Walley later became manager of the group.
 His surname has often been spelt incorrectly as 'Whalley' in numerous books and on web pages.
The Quarrymen (also written as "the Quarry Men") are a British skiffle/rock and roll group, formed by John Lennon in Liverpool in 1956, which eventually evolved into the Beatles in 1960.
 Originally consisting of Lennon and several schoolfriends, the Quarrymen took their name from a line in the school song of Quarry Bank High School, which they attended.
 Lennon's mother, Julia Lennon, taught her son to play the banjo and then showed Lennon and Eric Griffiths how to tune their guitars in a similar way to the banjo, and taught them simple chords and songs.
