IN: Gaelic Ireland (Irish: Eire Ghaidhealach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time. For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry.

For most of the Gaelic period, dwellings and farm buildings were circular with conical thatched roofs (see roundhouse). Square and rectangle-shaped buildings gradually became more common, and by the 14th or 15th century they had replaced round buildings completely. In some areas, buildings were made mostly of stone. In others, they were built of timber, wattle and daub, or a mix of materials. Most ancient and early medieval stone buildings were of dry stone construction. Some buildings would have had glass windows. Among the wealthy, it was common for women to have their own 'apartment' called a grianan (anglicized "greenan") in the sunniest part of the homestead.  The dwellings of freemen and their families were often surrounded by a circular rampart called a "ringfort". There are two main kinds of ringfort. The rath is an earthen ringfort, averaging 30m diameter, with a dry outside ditch. The cathair or caiseal is a stone ringfort. The ringfort would typically have enclosed the family home, small farm buildings or workshops, and animal pens. Most date to the period 500-1000 CE and there is evidence of large-scale ringfort desertion at the end of the first millennium. The remains of between 30,000 and 40,000 lasted into the 19th century to be mapped by Ordnance Survey Ireland. Another kind of native dwelling was the crannog, which were roundhouses built on artificial islands in lakes.  There were very few nucleated settlements in Gaelic areas. However, after the 5th century some monasteries became the heart of small "monastic towns". By the 10th century the Norse-Gaelic ports of Dublin, Wexford, Cork and Limerick had grown into substantial settlements. It was at this time, perhaps as a response to Viking raids, that many of the Irish round towers were built.  In the fifty years before the Norman invasion, the term "castle" (Old Irish: caistel/caislen) appears in Gaelic writings, although there are no surviving examples of pre-Norman castles. After the invasion, the Normans built motte-and-bailey castles in the areas they occupied, some of which were converted from ringforts. By 1300 "some mottes, especially in frontier areas, had almost certainly been built by the Gaelic Irish in imitation". The Normans gradually replaced wooden motte-and-baileys with stone castles and tower houses. Tower houses are free-standing multi-storey stone towers usually surrounded by a wall (see bawn) and ancillary buildings. Gaelic families had begun to build their own tower houses by the 15th century. As many as 7000 may have been built, but they were rare in areas with little Norman settlement or contact. They are concentrated in counties Limerick and Clare but are lacking in Ulster, except the area around Strangford Lough.  In Gaelic law, a 'sanctuary' called a maighin digona surrounded each person's dwelling. The maighin digona's size varied according to the owner's rank. In the case of a boaire it stretched as far as he, while sitting at his house, could cast a cnairsech (variously described as a spear or sledgehammer). The owner of a maighin digona could offer its protection to someone fleeing from pursuers, who would then have to bring that person to justice by lawful means.

IN: UFO are an English rock band that was formed in London in August 1969. They became a transitional group between early hard rock and heavy metal and the new wave of British heavy metal. The band's current lineup includes vocalist Phil Mogg, lead guitarist Vinnie Moore, bass guitarist Rob De Luca, keyboardist and rhythm guitarist Paul Raymond and drummer Andy Parker. They have gone through several line-up changes, leaving Mogg as the only constant member, and had two hiatuses (1983-1984 and again from 1989 to 1991).

Tensions had begun to grow between Mogg and Schenker in the late 1970s, possibly from Schenker often leaving before or during shows. Soon after UFO's show in Palo Alto, California on 29 October 1978, Schenker left the band. He made a brief return to the Scorpions before going on to form his own Michael Schenker Group.  After Schenker's exit, UFO rehired Paul "Tonka" Chapman on guitar who brought over unused track ideas from Lone Star's drummer Dixie Lee. Shortly after, they released their next LP, No Place to Run in January, 1980. Produced by former Beatles producer George Martin, No Place To Run failed to match up to the success of its predecessors, though it fractionally missed the UK Top 10. Paul Raymond left the band at the end of the No Place To Run tour and was replaced by John Sloman from Uriah Heep for a couple of months and then by former Wild Horses guitarist and keyboardist Neil Carter, who helped fill the void in the songwriting left by Schenker's departure. Carter debuted with UFO on stage at the three-day Reading Festival on 23 August 1980, when the band played as the Saturday night headline act. At the beginning of the following year, UFO released the self-produced The Wild, the Willing and the Innocent, which had a lighter pop rock sound, which was popular at the time. The album achieved mild success in the UK, reaching the UK Top 20, and the single "Lonely Heart" was released.  In February 1982 the band released Mechanix. It was very successful in the UK, where it reached No.8, the band's highest ever placing. Later that year, founding member Pete Way left the band to form Fastway with Motorhead guitarist "Fast" Eddie Clarke and then his own band, Waysted. He was replaced by Talas bassist, Billy Sheehan. UFO released Making Contact in 1983, but the album was a critical and commercial failure. Thus, that March, UFO decided to disband. The band played a UK farewell tour with Paul Gray (ex Eddie and the Hot Rods and The Damned bassist). However, there was a hint that this might not be permanent, when UFO released a compilation album featuring songs by UFO (as well as other groups featuring ex-members of UFO) entitled Headstone, the sleeve of which showed a headstone, denoting UFO with their formation date but an incomplete end date.  This proved to be a short hiatus as, just short of two years later, in late 1984, Mogg assembled a new UFO line-up, featuring Paul Gray on bass again, ex-Diamond Head drummer Robbie France (replaced in 1985 by former Magnum drummer Jim Simpson), and Atomik Tommy M (Tommy McClendon), a former roadie who also wrote lyrics for Loudness, on guitar, with Paul Raymond rejoining shortly after and released Misdemeanor. This was followed by the 1988 EP Ain't Misbehavin. Despite the renewed activity of the band, neither release was financially successful and they officially disbanded again in 1989 after a string of guitarists replacing McClendon: Myke Gray of Jagged Edge in late 1987, in 1988 former Legs Diamond guitarist Rik Sanford and Tony Glidewell, while Pete Way rejoined on bass, and finally in 1989 future Cold Sweat guitarist Erik Gamans.
