Liszt, thanks for the levity!

I suppose a song which comes to my mind in this conversation might be the John Prine and Iris Demente duo of "In Spite of Ourselves"
Find me two singers with grander accents, I dare ya.
But if you ever become familiar enough with the song (or enjoy it enough) to perform it, I would CHALLENGE you to pull it off with a non-southern accent. Doing so would brutally suck, as the accent is an essential element of the song.
