There's that song about rape from The Fantastiks.
There's 'Seasons in the sun' the pop tune lament of a dying man.
There's that song from The Gangs All Here, a Busby Berkley, Carmen Miranda Vehicle that they used as a setting for the Polka Dot Polka dance number. It had the memorable chorus...
If you wanna you can rhyme it with bazooka
But you can't pooh-pooh Paducah
Its another name for paradise.
And I still absolutely despise Stookey's 'The Wedding Song'.
