Question: Who is the father of the composer of the songs in the film Imagine?

full_context: Document 1: The Long and Winding Road: 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 his personal life was taking in the autumn of 1968, after he had separated from his fiancée Jane Asher, 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. ''

Leibovitz promised Lennon that a photo with Ono would make the front cover of the magazine, even though she initially tried to get a picture with Lennon by himself. Leibovitz said, "Nobody wanted [Ono] on the cover". Lennon insisted that both he and his wife be on the cover, and after taking the pictures, Leibovitz left their apartment at 3:30. After the photo shoot, Lennon gave what would be his last interview, to San Francisco DJ Dave Sholin, for a music show to be broadcast on the RKO Radio Network.

Document 11: I Dig Love: Leng draws parallels between "I Dig Love" and the Beatles' more free-form compositions of the late 1960s. Among these, Paul McCartney's "Why Don't We Do It in the Road?" exemplifies what Ian MacDonald termed in the 1990s the "long-gone let-it-all-hang-out era". In his book "Working Class Mystic", Gary Tillery identifies "I Dig Love" as one of two "All Things Must Pass" tracks (the other being "Wah-Wah") that could have been sung by John Lennon, whose style increasingly embraced provocative artistic statements following the start of his relationship with Yoko Ono in 1968. Leng also compares "I Dig Love" with "Love the One You're With", a "hymn to hedonism" by Stephen Stills, with whom Harrison worked on Doris Troy's eponymous album for Apple Records, in 1969–70.
Document 12: Mother (John Lennon song): "Mother" is a song by English musician John Lennon, first released on his 1970 album "John Lennon/Plastic Ono Band". An edited version of the song was issued as a single in the United States on Apple Records, on 28 December 1970. The single edit runs 1:41 shorter than the album due to removing the tolling bells that start the song and a quicker fade-out. The B-side features "Why" by Yoko Ono. The song peaked in the United States at number 19 on the "Cashbox" Top 100 and number 43 on the "Billboard" Hot 100.
Document 13: Jealous Guy: ``Jealous Guy ''is a song by English rock musician John Lennon from his 1971 album Imagine. Lennon began writing the song in 1968, when, as`` Child of Nature'', it was among the many songs demoed by the Beatles before they recorded their self - titled double album (also known as the ``White Album ''). The lyrics were originally inspired by a lecture given by Maharishi Mahesh Yogi in early 1968, when the Beatles attended his spiritual retreat in Rishikesh, India. In its rewritten form, the song serves as a confessional in which Lennon addresses the feelings of inadequacy that resulted in his failings as a lover and husband.
