Here are sample lyrics to well known tunes.

O mine eyes have seen the coming of the fumbling, mumbling Bush; He has babbled all the drivel that the Ne0-cons can push; He has lost signt of all reason 'cause his head is full of mush; False Faith goes marching on.
Glory Glory how he'll screw ya!... Dubya Doofus marches on.

Amazing George, with mind unsound. With kids when danger nears, He reads of goats with grinning gloats, Ignoring real fears.
When people vote, No paper note, Machines by Diebold. Control the count, let protests mount. The frauds by court uphold.

Onward, concerned Democrats Uphold our civil rights, Oppose corporate plutocrats and Neo-Con might.
We can stop the tyranny No homeland of fear. We are bond of many Together we can cheer..

Forward "We the People." Against corporate greed. Individuals enable meeting human need.

Oh beautiful Our Nation Conceived in liberty, For all by constitution with rights guaranteed..
Oh Democrats, all Democrats Gather in the big tent. We will be whole, by self control and govern by assent.
