input: The original line-up was formed in Houston and consisted of Gibbons, organist Lanier Greig (died February 2013) and drummer Dan Mitchell.  The name of the band was Gibbons' idea. The band had a little apartment covered with concert posters and he noticed that many performers' names utilized initials. Gibbons particularly noticed B.B. King and Z.Z. Hill and thought of combining the two into "ZZ King", but considered it too similar to the original name. He then figured that "king is going at the top" which brought him to "ZZ Top".  ZZ Top was managed by Bill Ham, a Waxahachie, Texas native who had befriended Gibbons a year earlier. They released their first single, "Salt Lick", in 1969, and the B-side contained the song "Miller's Farm". Both songs were credited to Gibbons. Immediately after the recording of "Salt Lick", Greig was replaced by bassist Billy Ethridge, a band-mate of Stevie Ray Vaughan, and Mitchell was replaced by Frank Beard of the American Blues. Due to lack of interest from U.S. record companies, ZZ Top accepted a record deal from London Records. Unwilling to sign a recording contract, Ethridge quit the band and Dusty Hill was selected as his replacement. After Hill moved from Dallas to Houston, ZZ Top signed with London in 1970. They performed their first concert together at the Knights of Columbus Hall in Beaumont on February 10.  In addition to assuming the role as the band's leader, Gibbons became the main lyricist and musical arranger. With the assistance of Ham and engineer Robin Hood Brians, ZZ Top's First Album (1971) was released and exhibited the band's humour, with "barrelhouse" rhythms, distorted guitars, double entendres, and innuendo. The music and songs reflected ZZ Top's blues influences. Following their debut album, the band released Rio Grande Mud (1972), which failed commercially and the promotional tour consisted of mostly empty auditoriums.

input: After his 2003 resignation from the Cabinet, Cook remained an active backbench Member of Parliament until his death. After leaving the Government, Cook was a leading analyst of the decision to go to war in Iraq, giving evidence to the Foreign Affairs Select Committee which was later relevant during the Hutton and Butler inquiries. He was sceptical of the proposals contained in the Government's Higher Education Bill, and abstained on its Second Reading. He also took strong positions in favour of both the proposed European Constitution, and the reform of the House of Lords to create a majority-elected second chamber, about which he said (while he was Leader of the Commons), "I do not see how [the House of Lords] can be a democratic second Chamber if it is also an election-free zone".  In the years after his exit from the Foreign Office, and particularly following his resignation from the Cabinet, Cook made up with Gordon Brown after decades of personal animosity -- an unlikely reconciliation after a mediation attempt by Frank Dobson in the early 1990s had seen Dobson conclude (to John Smith) "You're right. They hate each other." Cook and Brown focused on their common political ground, discussing how to firmly entrench progressive politics after the exit of Tony Blair. Chris Smith said in 2005 that in recent years Cook had been setting out a vision of "libertarian, democratic socialism that was beginning to break the sometimes sterile boundaries of 'old' and 'New' Labour labels". With Blair's popularity waning, Cook campaigned vigorously in the run-up to the 2005 general election to persuade Labour doubters to remain with the party.  In a column for the Guardian four weeks before his death, Cook caused a stir when he described Al-Qaeda as a product of a western intelligence:  Bin Laden was, though, a product of a monumental miscalculation by Western security agencies. Throughout the 80s he was armed by the CIA and funded by the Saudis to wage jihad against the Russian occupation of Afghanistan. Al-Qaeda, literally "the database", was originally the computer file of the thousands of mujahideen who were recruited and trained with help from the CIA to defeat the Russians.  Some commentators and senior politicians said that Cook seemed destined for a senior Cabinet post under a Brown premiership.

input: The first Muslim conquest of Sicily began in 827, though it was not until 902 that almost the entire island was in the control of the Aghlabids, with the exception of some minor strongholds in the rugged interior. During that period some parts of southern Italy fell under Muslim control, most notably the port city of Bari, which formed the Emirate of Bari from 847-871. In 909 the Aghlabid dynasty was replaced by Shiite Fatimids. Four years later, the Fatimid governor was ousted from Palermo when the island declared its independence under Emir Ahmed ibn-Kohrob. The language spoken in Sicily under Muslim rule was Siculo-Arabic.  In 1038, a Byzantine army under George Maniaces crossed the strait of Messina. This army included a corps of Normans that saved the situation in the first clash against the Muslims from Messina. After another decisive victory in the summer of 1040, Maniaces halted his march to lay siege to Syracuse. Despite his success, Maniaces was removed from his position, and the subsequent Muslim counter-offensive reconquered all the cities captured by the Byzantines.  The Norman Robert Guiscard, son of Tancred, invaded Sicily in 1060. The island was split between three Arab emirs, and the Christian population in many parts of the island rose up against the ruling Muslims. One year later, Messina fell, and in 1072 Palermo was taken by the Normans. The loss of the cities, each with a splendid harbor, dealt a severe blow to Muslim power on the island. Eventually all of Sicily was taken. In 1091, Noto in the southern tip of Sicily and the island of Malta, the last Arab strongholds, fell to the Christians. Islamic authors noted the tolerance of the Norman kings of Sicily. Ibn al-Athir wrote: "They [the Muslims] were treated kindly, and they were protected, even against the Franks. Because of that, they had great love for King Roger."  The Muslim problem characterized Hohenstaufen rule in Sicily under Holy Roman Emperors Henry VI and his son Frederick II. Many repressive measures were introduced by Frederick II to please the popes, who were intolerant of Islam in the heart of Christendom. This resulted in a rebellion by Sicilian Muslims, which in turn triggered organized resistance and systematic reprisals and marked the final chapter of Islam in Sicily. The complete eviction of Muslims and the annihilation of Islam in Sicily was completed by the late 1240s when the final deportations to Lucera took place.
