For the 30 days of music:
"In Spite of Ourselves" (song starts around 1:45, it's a live performance.)
Just read along with the lyrics, although you can easily follow along if you just listen. It's certainly good for a giggle, but I'll rate it 'PG' - there's no swearing or anything, but she does mention drinking and underwear (hers, specifically!) - so you might want to test-listen before listening it with kids around! ;-)
You know, I mentioned Dave & Marisa the other day.... well, this is "their" song! Played at their wedding and everything - and once again, it's their fault that I know and love this song.... and that's okay!
