"Hey Jude" is a song by the English rock band the Beatles, written by Paul McCartney and credited to Lennon-McCartney. The ballad evolved from "Hey Jules", a song McCartney wrote to comfort John Lennon's son, Julian, during his parents' divorce. "Hey Jude" begins with a verse-bridge structure incorporating McCartney's vocal performance and piano accompaniment; further instrumentation is added as the song progresses. After the fourth verse, the song shifts to a fade-out coda that lasts for more than four minutes. "
Having earmarked the song for release as a single, the Beatles recorded "Hey Jude" during the sessions for their self-titled double album, commonly known as "the White Album". The sessions were marked by an element of discord within the group for the first time, partly as a result of Ono's constant presence at Lennon's side, and also reflective of the four band members' divergence following their communal trip to Rishikesh in the spring of 1968 to study Transcendental Meditation. Author Peter Doggett describes the completed version of "Hey Jude" as a song that "glowed with optimism after a summer that had burned with anxiety and rage within the group". The Beatles first taped 25 takes of the song at EMI's Abbey Road Studios in London over two nights, 29 and 30 July 1968, with George Martin as their producer. These dates served as rehearsals, however, since they planned to record the master track at Trident Studios to utilise their eight-track recording machine (Abbey Road was still limited to four-tracks). A take from 29 July, which author and critic Kenneth Womack describes as a "jovial" session, was issued on the Anthology 3 compilation in 1996. The 30 July rehearsals were filmed for a short documentary titled Music! However, the film shows only three of the Beatles performing "Hey Jude", as George Harrison remained in the studio control room, with Martin and EMI recording engineer Ken Scott. Author Simon Leng views this as indicative of how Harrison was increasingly allowed little room to develop ideas on McCartney compositions, whereas he was free to create empathetic guitar parts for Lennon's songs of the period. During the rehearsals that day, Harrison and McCartney had a heated disagreement over the lead guitar part for the song. Harrison's idea was to play a guitar phrase as a response to each line of the vocal, which did not fit with McCartney's conception of the song's arrangement, and he vetoed it. In a 1994 interview, McCartney said, "looking back on it, I think, Okay. Well, it was bossy, but it was ballsy of me, because I could have bowed to the pressure." Ron Richards, a record producer who worked for Martin at both Parlophone and AIR Studios, said McCartney was "oblivious to anyone else's feelings in the studio", and that he was driven to making the best possible record, at almost any cost.

Did someone leave the band over the recording?

The Maya civilization was a Mesoamerican civilization developed by the Maya peoples, and noted for its hieroglyphic script--the only known fully developed writing system of the pre-Columbian Americas--as well as for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in an area that encompasses southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. This region consists of the northern lowlands encompassing the Yucatan Peninsula, and the highlands of the Sierra Madre, running from the Mexican state of Chiapas, across southern Guatemala and onwards into El Salvador, and the southern lowlands of the Pacific littoral plain. The Archaic period, prior to 2000 BC, saw the first developments in agriculture and the earliest villages.
The Maya developed their first civilization in the Preclassic period. Scholars continue to discuss when this era of Maya civilization began. Maya occupation at Cuello (modern-day Belize) has been carbon dated to around 2600 BC. Settlements were established around 1800 BC in the Soconusco region of the Pacific coast, and the Maya were already cultivating the staple crops of maize, beans, squash, and chili pepper. This period was characterized by sedentary communities and the introduction of pottery and fired clay figurines. During the Middle Preclassic Period, small villages began to grow to form cities. Nakbe in the Peten department of Guatemala is the earliest well-documented city in the Maya lowlands, where large structures have been dated to around 750 BC. The northern lowlands of Yucatan were widely settled by the Middle Preclassic. By approximately 400 BC, early Maya rulers were raising stelae. A developed script was already being used in Peten by the 3rd century BC. In the Late Preclassic Period, the enormous city of El Mirador grew to cover approximately 16 square kilometres (6.2 sq mi). Although not as large, Tikal was already a significant city by around 350 BC. In the highlands, Kaminaljuyu emerged as a principal centre in the Late Preclassic. Takalik Abaj and Chocola were two of the most important cities on the Pacific coastal plain, and Komchen grew to become an important site in northern Yucatan. The Late Preclassic cultural florescence collapsed in the 1st century AD and many of the great Maya cities of the epoch were abandoned; the cause of this collapse is unknown.

Was there a population of these cities?

The northern lowlands of Yucatan were widely settled by the Middle Preclassic.

Sydney Francis Barnes (19 April 1873 - 26 December 1967) was an English professional cricketer who is generally regarded as one of the greatest ever bowlers. He was right-handed and bowled at a pace that varied from medium to fast-medium with the ability to make the ball both swing and break from off or leg. He is the quickest bowler to achieve 150 Test wickets in history. Barnes was unusual in that, despite a very long career as a top-class player, he spent little more than two seasons in first-class cricket, representing Warwickshire and Lancashire.
Barnes' career began in 1888 when he was fifteen and played for a small club which had a ground behind the Galton Hotel in Smethwick. Soon afterwards, he joined Smethwick Cricket Club and played for its third team. He was taught to bowl off spin by Billy Bird, the Smethwick professional who had played for Warwickshire, and then taught himself to bowl leg spin. In due course, he was selected for the second team and had earned a place in the first team, playing in the Birmingham and District Premier League, at the start of the 1893 season. In 1894, when Barnes was a 21-year-old fast bowler, he was asked to join the ground staff of Staffordshire County Cricket Club but he found the terms unattractive. Instead, he joined Rishton Cricket Club in the Lancashire League where the pay was better than in any form of county cricket, largely because of match bonuses and collections. Wilfrid S. White commented that Barnes' career in league cricket "stands out unparalleled, unapproached, by any other player". Later in the 1894 season, Barnes was invited to play for Warwickshire, who were due to enter the County Championship in 1895. His debut was in a minor match against Cheshire at Edgbaston on 20-21 August. Barnes bowled only 8 overs, taking none for 27, and the match was drawn. On 23 August, Barnes made his first-class debut for Warwickshire against Gloucestershire at Clifton College Close Ground, except that he did not take the field as play was restricted by bad weather to just 72 overs of his team's first innings, in which they reached 102-2.
