Question: Which author wrote the novella which formed the basis for the Christmas television special that was accompanied by Kelly Clarkson's album "Wrapped in Red"?
Context: An American Idol Christmas (also titled A Very Idol Christmas in Canada) is a Christmas television special for the television shows "American Idol", "American Juniors" and "Canadian Idol", but focused mostly on "American Idol"– the Canadian winner Ryan Malcolm was edited out in the American release, due to legal reasons.  The special was broadcast on the Fox television network in the United States and CTV in Canada.  It was first broadcast on November 25, 2003 in the United States.  It featured some of the top finalists of American Idol's first season (Kelly Clarkson, Tamyra Gray, Christina Christian) and second season (Ruben Studdard, Clay Aiken, Kimberley Locke); "Canadian Idol" winner Ryan Malcolm (not shown in American version due to the upcoming World Idol); and the American Juniors.  Since the episode was not a competition, none of the judges appeared because they were working on the next season's contestants.  It was directed by Bruce Gowers, produced by 19 Entertainment, Fremantle Media North America, Cécile Frot-Coutaz, Simon Fuller, David Goffin, Nigel Lythgoe and Ken Warwick. A Christmas Carol in Prose, Being a Ghost-Story of Christmas, commonly known as A Christmas Carol, is a novella by Charles Dickens, first published in London by Chapman & Hall in 1843; the first edition was illustrated by John Leech.  "A Christmas Carol" tells the story of Ebenezer Scrooge, an old miser who is visited by the ghost of his former business partner Jacob Marley and the Ghosts of Christmas Past, Present and Yet to Come.  After their visits Scrooge is transformed into a kinder, gentler man. "Wrapped in Red" is a song by American recording artist Kelly Clarkson.  It is the titular song and the opening track from her sixth studio album, "Wrapped in Red" (2013).  Written by Clarkson, Ashley Arrison, Aben Eubanks, and Shane McAnally, the song is produced by Greg Kurstin, who recorded the track using the Wall of Sound production technique developed by Phil Spector.  A soul-pop ballad, "Wrapped in Red" is a Christmas song about unrequited love in the holidays, in which the color red is used as metaphorical device to express someone's truthful feelings, apart from being a quintessential holiday color.  "Wrapped in Red" was serviced by RCA Records to Adult Contemporary radio stations as the second single from the album on November 25, 2014. "Winter Dreams (Brandon's Song)" is a song by American recording artist Kelly Clarkson, from her sixth studio album, "Wrapped in Red" (2013).  Produced by Greg Kurstin, Clarkson co-wrote the song with Ashley Arrison and Aben Eubanks for her husband (then-fiancé) Brandon Blackstock, stepson of American recording artist Reba McEntire.  A slow-tempo Christmas neo-jazz pop song, "Winter Dreams" features a 50-piece chamber orchestra conducted and arranged by film composer Joseph Trapanese.  Its lyrical theme mainly depicts love and escapism during the holidays, in which Clarkson sings about spending her first holiday with Blackstock, whom the song is also dedicated.  Unlike the deep lyrical themes of "Every Christmas", in which she refers to her life before meeting Blackstock, Clarkson had described "Winter Dreams" with a lighter fare, referring to it as her holiday life after meeting him. Wrapped in Red is the sixth studio album by American singer Kelly Clarkson, released on October 25, 2013 by RCA Records.  The album is a follow-up to her first greatest hits album, "Greatest Hits – Chapter One", and its companion extended play, "The Smoakstack Sessions Vol.  2".  Produced by Greg Kurstin, it is her first Christmas album and her first record to be solely released by RCA.  "Wrapped in Red" consists of sixteen tracks, featuring five co-penned original songs and eleven cover versions of Christmas standards and carols, two of which are duets featuring recording artists Ronnie Dunn, Reba McEntire and Trisha Yearwood. "Just for Now" is a song by English recording artist and producer Imogen Heap, from her second studio album, "Speak for Yourself" (2005).  Written and produced by Heap, the song was originally written for the second-season episode of the television series "The O.C." entitled "The Chrismukkah That Almost Wasn't", but was deemed too dark for the episode.  "Just for Now" is a electronica song about a constant mayhem within a holiday environment, in which the singer sings to set aside the disarray for a short time of peace.  Heap has performed the song in live performances, which she invites the audience to participate on it.  "Just for Now" was covered by American recording artist Kelly Clarkson, for her sixth studio album "Wrapped in Red" (2013).  Her version of the song, produced by Greg Kurstin, musically quotes the Christmas standard "Carol of the Bells" and was met with positive reviews.  The song was also sampled in Clams Casino's composition "I'm God", featured on both "Instrumentals" and Lil B's "6 kiss", and was also covered by Pentatonix on their 2015 deluxe edition of their Christmas album That's Christmas to Me. "Underneath the Tree" is a song by American singer Kelly Clarkson, from her sixth studio album and first Christmas album, "Wrapped in Red" (2013).  Written by Clarkson along with Greg Kurstin, who handled its production, it is a Christmas-themed song that sings of gratitude for companionship during the holidays, in which the beloved is being referred as the only present needed "underneath the tree".  Accompanied by various instrumental sounds, the song prominently incorporates a Wall of Sound treatment along with sleigh bells and bell chimes to resonate a holiday atmosphere.  "Underneath the Tree" was first released to Adult Contemporary radio stations on November 5, 2013, by RCA Records as the lead single from the album. Kelly Clarkson's Cautionary Christmas Music Tale is a Christmas television special produced by Done and Dusted for NBC.  Directed by Hamish Hamilton, it stars Kelly Clarkson, Blake Shelton, Reba McEntire, Trisha Yearwood, Robin Williams, Whoopi Goldberg, William Shatner, Jay Leno, Matt Lauer, Danica Patrick, Heidi Klum, Ken Jeong, Jai Rodriguez and Morgan Bastin.  It is a musical comedy pastiche loosely based on Charles Dickens's "A Christmas Carol" where Clarkson's character learns the true meaning of Christmas, accompanied by the music of her sixth studio album "Wrapped in Red".  With its musical performances filmed live at The Venetian Las Vegas on October 30, 2013, the television special itself was broadcast on December 11, 2013 on NBC in the United States.  The special won a Gold World Medal for best Variety Special in the New York Festival’s International Television & Film Awards.  The special was aired on December 23, 2014 and December 17, 2015. "4 Carats" is a song by American recording artist Kelly Clarkson, from her sixth studio album, "Wrapped in Red" (2013).  Written by Clarkson, Cathy Dennis, Livvi Franc, with Greg Kurstin, who helmed the song's production.  A Christmas pop song, "4 Carats" was originally written for Clarkson's seventh studio album that would have followed-up "Wrapped in Red".  Lyrically, the song explores the themes of holiday gift giving and materialism, with the singer asking Santa Claus for a four carat gemstone ring for Christmas day.  Clarkson took inspirations from the songs "Santa Baby" (1953) and "Material Girl" (1984), sung by Eartha Kitt and Madonna, respectively, and described it as a crossover between the two. Miracle on Broadway is an annual Christmas benefit concert by American recording artist Kelly Clarkson.  Presented by Live Nation, the first of a planned annual series of benefit concerts was held at the Bridgestone Arena in Nashville, Tennessee on December 20, 2014 and featured musicians Reba, Trisha Yearwood, Garth Brooks, Ronnie Dunn, Kacey Musgraves, Hayley Williams, Chad Gilbert, Charles Esten, Meghan Trainor, Martina McBride, Kix Brooks, and Deborah Allen performing renditions of various Christmas songs and tracks from Clarkson's Christmas album "Wrapped in Red" (2013).  The concert raised over US$500,000 ticket sales and donations for four charities based in Nashville: Monroe Carell Jr.  Children's Hospital at Vanderbilt, Monroe Harding Children’s Home, Second Harvest Food Bank, and Thistle Farms.  Clarkson had also announced plans to turn Miracle on Broadway into an annual benefit concert and planned to hold one in Bridgestone Arena on December 18, 2015.  However, this concert was cancelled due to Clarkson's health problems.  The 2016 concert was held on December 16, 2016.
