Passage: Potter was born in Bedford to Reverend Brignal Peel, a Wesleyan minister, and Elizabeth Stimson. He was educated at Bedford Modern School and for a time at Worcester College, Oxford. He first performed in E. M. Royle's The White Man at the Lyric Theatre in London before touring. In 1915 he was George Robey's understudy at the Alhambra. During the Great War Potter served as a 2nd lieutenant in the Royal Field Artillery in France. He served in the 6th Division 2nd Brigade 21st Battery, from 8 February 1917 before returning to music hall once the war was over. Potter cultivated an individual style and persona, wearing a straw boater, wide grey flannel trousers (he said he invented the Oxford bags style at the Coliseum in 1920), an 'Old Borstolian' blazer and carrying a notebook with a rolled umbrella. James Agate described him as "that sham Harrovian who bears upon his blazer the broad arrows of a blameful life".

Passage: On 15 February 2016, McCartney announced two initial festival dates in Europe for the upcoming summer. These two headlining performances at Pinkpop Festival in Landgraaf, Netherlands and Rock Werchter in Werchter, Belgium were revealed before the initial revelation of the "One on One" tour. These tours would feature mostly similar elements of the "One on One" performances yet with a condensed set list to allot for festival curfew limits and less stage elements given restrictions. In the wake of the passing of notable Beatles and McCartney producer George Martin, McCartney announced the initial "One on One" dates for North America and Europe. In North America, McCartney's visit to Fresno, California would mark his first performance in the city, and his performances in North Little Rock and Sioux Falls would be his first performances in the states of Arkansas and South Dakota respectively. Elsewhere in North America, McCartney would perform in Portland after an eleven-year absence following his 2005 'US' tour. The two shows in Vancouver would follow his previous performance in the city at the BC Place stadium in 2012, yet this tour would feature two shows in the neighboring Rogers Arena after the pyrotechnics during his concert at BC Place accidentally damaged the stadium's new roof. McCartney's Seattle show would mark his shortest absence from any North American city on the tour announced currently, as he performed at the city's Safeco Field during the inaugural year of the 'Out There' tour. McCartney announced a performance on 16 March in Minneapolis at the Target Center. This show would take place on 4 May 2016, less than two years after McCartney's last performance in the city at the adjacent baseball stadium sharing a corporate sponsor with the arena, Target Field. Due to high demand of tickets a second show in Minneapolis was announced the next day and would take place on 5 May.
Link Information: BC Place was built as part of the preparations for the 1986 World's Fair, Expo 86. Upon its completion in 1983 Question: Which Vancouver stadium that McCartney played at is newer?
Answer: Rogers Arena

Passage: The main party left England by sea on 20 January 1933, stopping at Gibraltar, where the Rock of Gibraltar "offered a climbing problem or two", and Aden. Time at sea was spent discussing the problem of climbing Mount Everest and the establishment of the various camps on its northern side, as well as learning the Nepali language, in which Crawford was proficient. The party alighted at Bombay, where they were assisted by C. E. Boreham, the manager of the Army and Navy Stores. Ruttledge, an India hand, took them on sightseeing tours to Agra and Fatehpur Sikri. Passing through Calcutta, where they were entertained by the Governor of Bengal, Sir John Anderson, the expedition members proceeded to Darjeeling, where Smythe, Greene and Birnie joined them, while Ruttledge went to Siliguri to rendezvous with Shebbeare and discuss transport arrangements. At Darjeeling porters were selected for the march, Ruttledge's Sherpas from his 1932 trip, Nima Dorje and Sanam Topgye, having gone to Sola Khombu to alert prospective applicants to the existence of the British expedition. Llakpar Chedi, Lewa and Nursang were selected as sirdars. In addition, Nima Tendrup, a veteran of many expeditions to Mount Everest, as well as a number of Sherpas who had been on the recent German expeditions to Kangchenjunga, were brought along. Karma Paul, who had been on the 1922 and 1924 British expeditions, was taken as interpreter. All the porters were screened at the Darjeeling hospital, 34 per cent being found to be infected with internal parasites, and then clothed in blue-and-white striped pyjamas and given numbered identity disks.
