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...

Paducah, Paducah.

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'.
