Just thought of another one: “The Morning After” was written for The Poseidon Adventure and performed (or lip-synched) by Carol Lynley for a rehearsal as well as the New Year’s Eve party.
On a technicality, there’s Can You Read My Mind from SUPERMAN.
The songs from Three Amigos. Wonderful homages / parodies of singing-cowboy era songs that were written for the movie.
Three Amigos Theme
My Little Buttercup
Blue Shadows
“Baby, Can You Dig Your Man?” from Stephen King’s The Stand.
“Always Look on the Bright Side of Life” from Monty Python’s Life of Brian.
“Stuck in the Middle With You” from Reservoir Dogs, which is playing on the radio during the torture scene.
The Oscar-winning “It’s Hard Out Here for a Pimp” from Hustle & Flow and the Oscar-nominated “Beautiful Maria of My Soul” from The Mambo Kings.
Streets of Fire closes with the lead actress singing “Tonight Is What It Means To Be Young”, written by Jim Steinman for the film.
“The lead actress” = smoking hot 19 year old Diane Lane <3
It’s been a long time since I saw the film (I mostly remember it as being a straight role for Rick Moranis), but I do remember she was hot.
“Nowhere Fast” and “I Can Dream About You”, from the same movie, are also pretty integral to the plot, and I came here specifically to mention that movie.
“Bedazzled” sung by Peter Cooke
Rebels are we from sleeper
Gonna see miss Liza from Take the money and run
The Michigan Rag from One Froggy Evening
Nat ‘King’ Cole and Stubby Kaye filling in the story between parts in Cat Ballou.
“Miss Celie’s Blues” from The Color Purple
Would “Moon River” from Breakfast at Tiffany’s count? The lyrics aren’t important, but the song advances the plot.
“Man of Constant Sorrow,” from O Brother, Where Art Thou?
“Throw the Jew down the Well” in Borat.
“Love Power” and “Prisoners of Love” in The Producers (“Springtime for Hitler” has already been mentioned).
“Sweetheart Tree” and “He Shouldn’t-a, Hadn’t-a, Oughtn’t-a Swang on Me” from The Great Race.
“The Power Of Love” in BACK TO THE FUTURE.
How much of the music in Saturday Night Fever was written specifically for the movie?
That song came out 30 years prior to the movie.
That’s traditional.
“Eee-O-Eleven” from the original Ocean’s Eleven is used as a kind of code.
