约翰-列侬(John Lennon)之子朱利安-列侬(Julian Lennon)为露西-沃顿(Lucy Vodden)发行了一首致敬单曲，这位女士是甲壳虫乐队歌曲《Lucy in the Sky with Diamonds》中的主人公，她在2009年9月因狼疮病去世。 朱利安-列侬同另一位曲作者詹姆斯-斯科特-库克(James Scott Cook)此前创建了一个慈善组织，该组织旨在研究治疗狼疮病。库克表示，这首单曲为纪念露西而作，同时也希望能够让更多的人了解到如何防御并治疗狼疮。最初朱利安仅仅是打算为这首单曲中录制背景和声，但是他在制作人托德-米格尔(Todd Meagher)的建议下，完整的演唱了整首歌曲。 单曲《Lucy》是朱利安-列侬近十年以来首次发行新歌曲。 "Lucy" is a song written and performed by Julian Lennon and James Scott Cook. The song is a sort of follow-up to The Beatles' "Lucy in the Sky with Diamonds", originally inspired by a drawing by a then four-year-old Lennon given to his father. The drawing was inspired by Lucy Vodden, a child friend of Lennon, and this song is dedicated to her. Lennon contacted his childhood friend Lucy later in life, and learned she had contracted the auto-immune disease lupus which she eventually died from. Proceeds from sales of the song and the EP release will go to two lupus charities, St. Thomas' Lupus Trust in the United Kingdom and the Lupus Foundation of America.
