While Mister Matt was thinking about WHISTLE DOWN THE WIND:
There was also "No Matter What" (the hopeful children's anthem, and the grown-up's angry manhunt), as well as "You Gotta Wrestle With the Devil!" Try adding those things to your "Angry Mob Song" list, EugLoven!
My favorite town songs were written by Menken and Ashman:
"Skid Row" from LSOH
and of course "Belle" from BATB.
And how about the lost Jim Steinman gem, "Garlic" from DOTV?
Or "Is That Remarkable" from FLOYD COLLINS?
"96,000" from IN THE HEIGHTS?
The opening to HELLO DOLLY before whoever plays Dolly comes out to screaming applause ("Call on Dolly! She's the one that spinsters recommend, etc.")
But, I believe, South Fl Marc, the title to the song that you were trying to bring up is "Get Me To the Church on Time." That song's title has been largely misattributed to "I'm Getting Married in the Morning" as it is the first line in the refrain, but [to quote David Tomlinson in a movie that is highly irrelevant] that is ENTIRELY beside the point. I should mention My Fair Lady also has the town singing "Wouldn't It Be Loverly" and "With a Little Bit O' Luck."
And I don't think anybody has brought up CONSIDER YOURSELF from Oliver!
