input question: The answer to the question: What is the last name of the person at whose farm "The Long and Winding Road" was written? is inside the article: Paul McCartney said he came up with the title "The Long and Winding Road" during one of his first visits to his property High Park Farm, near Campbeltown in Scotland, which he purchased in June 1966. The phrase was inspired by the sight of a road "stretching up into the hills" in the remote Highlands surroundings of lochs and distant mountains. He wrote the song at his farm in 1968, inspired by the growing tension among the Beatles. Based on other comments McCartney has made, author Howard Sounes writes, the lyrics can be seen as McCartney expressing his anguish at the direction of his personal life, as well as a nostalgic look back at the Beatles' history. McCartney recalled: "I just sat down at my piano in Scotland, started playing and came up with that song, imagining it was going to be done by someone like Ray Charles. I have always found inspiration in the calm beauty of Scotland and again it proved the place where I found inspiration."Once back in London, McCartney recorded a demo version of "The Long and Winding Road" during one of the recording sessions for The Beatles. Later, he offered the song to Tom Jones on the condition that the singer release it as his next single. In Jones' recollection, he was forced to turn it down since his record company were about to issue "Without Love" as a single.The song takes the form of a piano-based ballad, with conventional chord changes. McCartney described the chords as "slightly jazzy" and in keeping with Charles' style. The song's home key is E-flat major but it also uses the relative C minor. Lyrically, it is a sad and melancholic song, with an evocation of an as-yet unrequited, though apparently inevitable, love. In an interview in 1994, McCartney described the lyric more obliquely: "It's rather a sad song. I like writing sad songs, it's a good bag to get into because you can actually acknowledge some deeper feelings of your own and put them in it. It's a good vehicle, it saves having to go to a psychiatrist."The opening theme is repeated throughout. The..., can you guess it ????

Answer: "No Line on the Horizon 2"

Problem: Given the question: The answer to the question: What animals' flocks make a quiet chattering sound while at rest? is inside the article: The territorial call of the Australian raven is a slow, high ah-ah-aaaah with the last note drawn out. It uses this call to communicate with other Australian ravens in the area. When giving this call, the species has a horizontal posture, holding its head forward and body parallel to the ground, while perched on a prominent position. It ruffles its hackles and lowers its tail, and sometimes holds its beak open between calls. In contrast, the little raven and forest raven hold their bodies in an upright posture. This call becomes louder if trespassers encroach upon the Australian raven's territory. The five Australian species are very difficult to tell apart, with the call being the easiest way to do so, although the drawing-out of the final note—long held to be solely recorded for the Australian raven—has been recorded for the other species and is hence not diagnostic.The volume, pitch, tempo and order of notes can be changed depending on the message the Australian raven intends to convey. There is a variety of contact calls: a pair often makes a low murmuring sound when preening each other while roosting, and members of a flock carry on with a quiet chattering while at rest. Birds make a call and answer sequence if temporarily out of sight of one another while foraging. Birds in flocks make a single high-pitched caa while flying over another territory as a transit call to signify they are just passing through. An Australian raven will give a longer caa with a downward inflection to signify its return to the nest to its mate., can you guess it ?
