Here is a listing of some of the songs from Dicken's Christmas Carol, along with some information about where they came from. Feel free to add and comment if you can think of others.
"December the 25th"; "Thank You Very Much"( Scrooge: The Musical. a 1992 stage musical with book, music and lyrics by Leslie Bricusse.[1] It was adapted from the 1970 film Scrooge starring Albert Finney.)
"Ave Maria" (Trad. Schubert?)
"When Christmas Comes to Town" (Polar Express)
"You're a Mean one, Mr. Scrooge" (Adapted from The Grinch who Stole Christmas)
"Somewhere in my Memory" (by John Williams, Home Alone Movie Soundtrack)
"Little Altar Boy" (Written in 1961 by Howlett Smith, recorded by Andy Williams, Glen Campbell, The Carpenters, etc. Featured in the movie "Don't Knock the Twist".)
Nice research, and information! ;D
These songs definitely set the mood for the holiday season. I absolutely love just about everything composed by John Williams, but "Somewhere in My Memory" still gets me every time. :)
