[Q]: Question: How long had Prüm Abbey existed when Eygilo left to become the abbot of Flavigny? Passage:The fame of Flavigny was due partly to the relics which it preserved, and partly to the piety of its monks. The monastery was at the height of its reputation in the eighth century, in the time of the Abbot Manasses, who was appointed by Pippin the Short. In 760/62, Manasses attended the council of Attigny. Pippin's successor, Charlemagne, authorized Manasses to found the Carolingian style monastery of Corbigny. The same Manasses transferred from Volvic to Flavigny the relics of Saint Praejectus. Abbot Apollinaris, appointed by Charlemagne in 802, was also abbot of Saint-Bénigne de Dijon and Môutier-Saint-Jean. Charlemagne's son, Louis the Pious, used Abbot Adrevaldus as an envoy to Septimania in 834 and 838, according to the Historia Hludowici imperatoris. However, these dates do not correspond to those given in the abbey's only list, which says that Adrevaldus became abbot in 839 and ruled for three years. Eygilo, the founder of Prüm Abbey, left his own establishment to become abbot of Flavigny in 860. He set up monks at Corbigny, but later left Flavigny when he was appointed Archbishop of Sens. His successor, Geylo, resigned to become abbot of Tournus and was later appointed bishop of Langres.

[Q]: Question: How big is the National Park that the Yellowstone River flows northward through? Passage:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.

[Q]: Question: How old was John Cale the year that Uropa Lula opened for him in London? Passage:In 1980, Lloyd formed Uropa Lula with Hilde Swendgaard (manager) and Kevin Smith (drums), making two short films, "Here in the Sun" and "At Night Time" with Video Active. They were joined by Colin Prior (bass) and Peter Fromm (keyboards) in 1981 and began performing live in London, opening for John Cale, Alternative TV and Depeche Mode. American bass player Allan Dias replaced Prior in August of the same year. In September, the band recorded three songs, "Here's a Medal", "Timber Fall" I and "My Black Hour" for the Nicky Horne Capital Radio show. Leeds-born drummer Andrew Edge joined the group later that year. Uropa Lula signed to Arista Records in May 1982 and spent the rest of that year recording album tracks and their first two singles, "Our Love Has Just Begun" and "Fell Upon a Jewel" at Trident Studios, The Manor Studio, Townhouse Studios and RAK Studios. To tie in with the release of the first single, the band recorded a live session for the David Jensen show on Radio 1 for the BBC. The session was produced by Dale Griffin, the English drummer and founding member of 1970s rock band Mott the Hoople and featured two songs, "Here's a Medal" and "Timber Fall I". A month later, Uropa Lula returned to London's Capital Radio to record their second live session for the Nicky Horne show playing two songs, "I Am My Older Brother" and "Leather and Metal (Winter's Here)". In the fall of 1982, guitarist Chester Kamen and keyboard player Carol Isaacs joined the group in time for tours of the UK and US in 1983. The group's opening US show was at the Ritz in New York (1 February 1982). This was followed by dates at the Mudd Club (7 February 1982), the in Washington, D.C., the New Jersey City Gardens and a show at the Brooklyn Zoo (26 February 1982) where they shared the bill with Holly and the Italians. Upon their return to the UK, on 2 June 1982 the group played at the Camden Palace (now called Koko) and opened for Big Country at the Royal Court Theatre, Liverpool (19 June 1982) and John Cale at The Venue, Victoria, London (5 July 1982). With some irony, the band had by this point changed their name to Viva Lula and as part of the promotion of their third single, "Dad Sings the Blues"; they toured the UK with Big Country in June 1983. Lloyd disbanded the group in October 1983 and embarked on a solo career, albeit continuing to work with Uropa Lula members Kamen, Dias and Smith throughout the '80s.
