There's a difference between favorite song and the best song ever.
My favorite song is <a href="http://www.youtube.com/watch?v=bGA9WV1p-B4">"Thirsty Boots" by Eric Andersen</a>. (link is to a video of me performing it)
<i>You've long been on the open road, sleeping in the rain
From dirty words and muddy cells, your clothes are smeared and stained
But the dirty words and muddy cells will soon be judged insane
So only stop and rest yourself and you'll be off again.
CHORUS:
Take off of your thirsty boots and stay for awhile
Your feet are hot and weary from a dusty mile
And maybe I can make you laugh, and maybe I can try
Looking for the evening and the morning in your eyes.
Tell me of the ones you've seen as far as you could see
Across the plains from field to town a-marchin' to be free
And of the rusted prison gates that tumble by degree
Like laughing children one by one, they look like you and me.
CHORUS
I know you are no stranger down the crooked rainbow trails
From dancing cliff-edge shattered sills of slander-shackled jails
Where the melodies drift up from below, as walls are being scaled
Yes, all of this, and more my friend, your song shall not be failed.
CHORUS</i>
I think the "best song ever" would be <a href="http://www.youtube.com/watch?v=QHkT2YfqHE4">Don McLean's "American Pie"</a>. I won't post those lyrics, because they're too long.
