The Tripwire has an exlcusive mp3 of Justin Townes Earle and Dawn Landes perfomring "Do I Ever Cross Your Mind:" on their website! What a great tune!
Speaking of Dawn Landes, those of you that are unfamiliar with her (such as myself...), a nice interview with her appears in this month's Amercian Songwriter. It's a good introduction to what she is about. You can read the interview here.
