I love Kelly Hogan's voice. She can make anything sound magical - if you don't believe me one day I'll post her version of "Rubber Duckie" from Sesame Street. It will make you wish you were cute and yellow and chubby too (and if you already are, you can pretend she is singing it just for you). Unfortunately I'm only one of the three.
Here are two other cover versions: "Papa was a Rodeo", originally by the Magnetic Fields, and "Dues", taken from a remake of the soundtrack to Robert Altman's "Nashville" which also features Carolyn Mark, Neko Case and others.
