Example Input: Question: What year did Cash record "Big Iron"? Passage:Robbins has been honored by many bands, including the Grateful Dead who covered "El Paso" and Bob Weir & Kingfish who covered "Big Iron". The Who's 2006 album Endless Wire includes the song "God Speaks of Marty Robbins". The song's composer, Pete Townshend, explained that the song is about God deciding to create the universe just so he can hear some music, "and most of all, one of his best creations, Marty Robbins." The Beasts of Bourbon released a song called "The Day Marty Robbins Died" on their 1984 debut album The Axeman's Jazz. Both Frankie Laine and Elvis Presley, among others, recorded versions of Robbins' song "You Gave Me a Mountain", with Laine's recording reaching the pop and adult contemporary charts in 1969. Though Elvis never recorded any of Robbins' songs in the studio, he was a big fan and recorded "You Gave Me a Mountain" live in concert several times; it appeared on 15 Presley albums. Johnny Cash recorded a version of "Big Iron" as part of his American Recordings series, which is included in the Cash Unearthed box set. Cash also recorded other songs by Robbins, including "I Couldn't Keep From Crying", "Kate" and "Song Of The Patriot". He held Robbins in high esteem, having him guest several times on his network TV show. "Big Iron" was also covered by Mike Ness on his album Under the Influences, on which he paid homage to country music artists. The song, originally released on Robbins' 1959 album Gunfighter Ballads and Trail Songs, gained renewed popularity following its use in the video game .

Example Input: Question: Who was the chief editor of the Sydney morning Herald in 1954? Passage:Elizabeth II was the first reigning monarch of Australia to set foot on Australian soil, coming ashore at Farm Cove, Sydney, on 3 February 1954. She had two years earlier been en route to Australia when her father died while she was on a private visit to Kenya, forcing her to return to the United Kingdom. Once finally in Australia, with her husband the Duke of Edinburgh, she undertook a journey through the Australian Capital Territory, New South Wales, Tasmania, Victoria, Queensland, South Australia and Western Australia, including greeting 70,000 ex-servicemen and women at the Melbourne Cricket Ground and opening the Australian Parliament in Canberra. In all, the Queen travelled 10,000 miles by air, making approximately 33 flights, 2000 miles by road (130 hours in cars in 207 trips), visiting all capitals except Darwin and 70 country towns, many by special "royal trains". On one such train trip they visited Leuralla, at Leura, in the Blue Mountains. Twenty-seven years earlier, Harry Andreas of Leuralla had acted as a fishing guide for The Queen's parents, whilst the young Princess "Lillibet" was left at home with her grandparents, King George V and Queen Mary. This extensive travel allowed some 75 per cent of the Australian population to see the Queen at least once during the tour. At the conclusion of the tour the Prime Minister, Robert Menzies, stated in an article published in the Sydney Morning Herald:
