[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 SeptemberOctober 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 19721973.

[Q]: Question: What was the inaugural year of the race where Boreal made his first appearance outside Germany? Passage:On his first race of 2002, Boreal made his first appearance outside Germany when he contested the Dubai Sheema Classic at Nad Al Sheba Racecourse on 23 March. Ridden by Kieren Fallon, he stayed on strongly in the straight and finished third behind Nayef and the New Zealand gelding Hades with the other beaten horses including Marienbard and Tobougg. On 7 June, the colt was sent to England and attempted to become the first German-trained horse to win the Coronation Cup over one and a half miles at Epsom Racecourse. Racing on soft ground, he started 4/1 third favourite behind Kutub (Preis von Europa, Gran Premio del Jockey Club, Singapore Gold Cup), and Storming Home. The other three runners were Marienbard, Zindabad (Yorkshire Cup), and Pawn Broker (Arc Trial). Fallon positioned the German challenger just behind the leader Zindabad before taking the lead entering the straight and tracking across to the stands-side (outside) rail. Boreal went clear of his rivals in the last quarter mile and won by three and a half lengths from Storming Home with Zindabad six lengths back in third. After training the first German winner at Group One level in Britain since Star Appeal took the 1975 Eclipse Stakes, Schiergen said, "He travels smoothly on good ground but is more at home on soft. It's a special thrill to have a winner in Britain, and extra-special when it's a Group 1 at the home of the Derby."
