Other than "Shimmy...". Allison has recorded at least a couple of Christmas tune duets. One was with Alan Jackson (can't remember tune name) and one with another Country female artist (can't remember her name either). Boy I'm a lot of help!
Also, if memory serves (doubtful) there was a blog and/or FaceBook or MySpace page wanting Krauss to record an entire Christmas album.
I'm too busy slacking at work to look anything up at the moment. My boss is standing next to me texting on her Blackberry. Maybe I should ask her.
To coincide with today’s release of their new album, PAPER AIRPLANE, Alison Krauss & Union Station featuring Jerry Douglas will be performing new music on Wednesday, 4/13 on Late show with David Letterman, and on Thursday, 4/14 on NBC’s The today show.
