[Q]: Question: What other famous people came out of where The Beatles were based? Passage:The recordings made by the Beatles, a rock group from Liverpool, England, from their inception as the Quarrymen in 1957 to their break-up in 1970 and the reunion of their surviving members in the mid-1990s, have huge cultural and historical value. The studio session tapes are kept at Abbey Road Studios, formerly known as "EMI Recording Studios," where the Beatles recorded most of their music. While most have never been officially released, their outtakes and demos are seen by fans as collectables, and some of the recordings have appeared on countless bootlegs. Until 2013, the only outtakes and demos to be officially released were on The Beatles Anthology series and its tie-in singles, and bits of some previously unreleased studio recordings were used in video game as ambient noise and to give songs studio-sounding beginnings and endings. In 2013, Apple Records released the album The Beatles Bootleg Recordings 1963, which includes previously unreleased outtakes and demos from 1963, to stop the recordings from falling into the public domain.

[Q]: Question: How many battles had Oswald Watt commanded by the year Holden joined the Australian Imperial Force? Passage:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No.2 Squadron. Commanded by Major Oswald Watt, No.2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

[Q]: Question: What years was Billy Hughes the prime minister? Passage:Billy Hughes was a former prime minister who had been successively a member of the Labor Party, the National Labor Party, and the Nationalist Party. By 1928, he was the de facto leader of a group of backbenchers hostile to the government of Stanley Bruce (who had replaced him as Nationalist leader in 1923). He and his supporters began to frequently cross the floor and vote against the government, particularly on the controversial subject of industrial relations. On 22 August 1929, Hughes and Edward Mann were expelled from the Nationalist Party for voting in favour of an unsuccessful censure motion against the government. Tensions finally came to a head on 10 September, when Hughes successfully moved an amendment to the government's flagship Maritime Industries Bill. Bruce took this to be a vote of no confidence, and called an election for 12 October. Labor under James Scullin won a landslide victory, while Hughes and two other ex-Nationalists were re-elected as independents.
