Q: Question: In what year did Porter handle the sound duties for Ann-Margret? Passage:In December 1969, Presley called Porter to ask him to fix the sound for him in the main showroom at the International Hotel (renamed the Las Vegas Hilton two years later); he said he could not hear himself the last time he sang there, and a new run was scheduled for January. Porter went to see Presley's first rehearsal there, and found three stage monitors hanging high above the stage, with only one working. The hotel's engineers did not get the other two to work, so Porter had some of his own Shure Vocal Master loudspeakers brought over from the recording studio. He laid the column loudspeakers on their sides at the front lip of the stage and propped them up to aim at Presley, who was very happy with the result. Presley insisted upon having Porter mix his live show in January even though he was a recording engineer with no previous experience in live sound. Porter quickly learned about acoustic feedback during the first song, but backstage after the show, film stars and musical artists kept complimenting Presley, telling him that Porter’s concert sound was "just like the album". Porter mixed Presley's live concerts from then on. Presley paid Porter well for a touring sound engineer; a 1974 contract for nearly two weeks of touring during September–October netted Porter $2,600, an amount equivalent to $ in current value. Porter recorded several of these shows in the mid-1970s, released as albums, and witnessed firsthand Presley's physical decline from drug abuse. In 1975, Presley's doctors advised him to exercise more, so he had a racquetball court built at his mansion Graceland. Porter designed and supervised the installation of a powerful high-fidelity Electro-Voice loudspeaker sound system for the racquetball court and an adjoining lounge. On tour, Porter specified the best-sounding, most roadworthy equipment that existed: he used a Midas PRO4 mixing console and UREI equalizers. The tour was supported by Clair Brothers, who supplied all the audio gear and a monitor engineer, Bruce Jackson, who designed a powerful stage monitor system for Presley's show. In August 1977, Porter was changing planes in Boston to fly to Portland, Maine, to mix a Presley concert when he received a phone call informing him that the singer had died. He attended Presley's heavily guarded funeral ceremony at Graceland. Between Presley appearances, Porter also handled sound duties for Ann-Margret in Las Vegas and on the road, under the business name Captain Audio Productions. He consulted on television specials for Ann-Margret and for Bob Hope in 1972–1973.


A: Between Presley appearances, Porter also handled sound duties for Ann-Margret in Las Vegas and on the road, under the business name Captain Audio Productions

Q: Question: What is the current capital of the Asian country that Cretin thought about traveling to as a missionary? Passage:He was born in Montluel, in the département of Ain, France, 19 December 1799. He lived at St. Paul, Minnesota, 22 February 1857. He made his preparatory studies in the Petits séminaires of Meximieux (Ain) and Saint-Genis-l'Argentière (Rhône), his studies of philosophy at Alix (Rhône), and of theology in the seminary of Saint-Sulpice, Paris. He was ordained priest 20 December 1823, and soon was appointed vicar in the parish at Ferney, once the home of Voltaire, and eventually became its parish priest. He built there a new church and founded a boys' college with funds gathered on a tour through France. At this period, he revived the Catholic faith among many indifferent parishioners, who were made indifferent by the surviving influence of Descartes, and the proximity of the Protestant cantons of Switzerland. But Crétin longed for a larger field of activity; at one time he thought earnestly of going as a missionary to China. His perplexities in that regard were solved by the advent of Bishop Mathias Loras, first bishop of Dubuque, Iowa, who arrived in France in 1838 in search of priests for to evangelize his vast diocese. Crétin was one of the few who volunteered and on 16 August 1838, he secretly left his parish, embarked at Le Havre with Bishop Loras, and landed in New York in October of the same year. The winter of 1838-39 was spent in St. Louis, Missouri, and on his arrival in Dubuque, 18 April 1839, he was immediately appointed vicar-general of the new diocese. For over eleven years, he exercised his priestly ministry in these new regions, dividing his time between Dubuque, Prairie du Chien, Wisconsin, and the Winnebago Indians in the neighborhood of Fort Atkinson, in Winneshiek County, Iowa. Only once, in 1847, did he absent himself, when he made a trip to Europe in the interest of his missions. In 1850 St. Paul, Minnesota became the seat of a new diocese. Crétin was appointed its first bishop, and went to France, to be consecrated, 26 January 1851, at Belley by Bishop Devie, who had ordained him to the priesthood.
