While their first choice for the duet was Elton John, they chose country singer Bryan White. Twain later described White as`` the best male voice in country music. Beyond country music! He's an excellent singer. So he needed to be on this record, because the song soars. It demands that. It demands dynamics.''

Document 14: 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. ''
