The page I linked at the end of the previous entry is part of a treasure trove of lyrics of old-timey songs, with MIDI files accompanying most of them. To give you a sense of the selection, I'll pick a title from (almost) each letter of the alphabet:

Across the Alley from the Alamo
Believe Me If All Those Endearing Young Charms
Come Josephine in My Flying Machine
Don't Fence Me In
Embraceable You
Faded Love
Glow Worm
Hello My Baby
I Only Have Eyes for You
Jeepers Creepers
K-K-K-Katy
Lovesick Blues
Mairzy Doats
Night and Day
On the Atchison, Topeka, and Santa Fe
Pick Yourself Up
Red River Valley
Smoke, Smoke, Smoke That Cigarette
Tenderly
Up a Lazy River
Violets for Your Furs
We'll Meet Again
Yes, We Have No Bananas
Zip-a-Dee-Doo-Dah

Quite a variety -- blues, Western Swing, Tin Pan Alley, Cole Porter, Johnny Mercer, musical theatre, and Disney movies.
