Task: Question Answering
Input (English): Passage: 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 song lacks a traditional chorus, and the melody and lyrics are ambiguous about the opening stanza's position in the song; it is unclear whether the song has just begun, is in the verse, or is in the bridge. 
Question: What is the last name of the person who was inspired to write a song by the growing tension among the Beatles?
Output (English): McCartney.
