I just finished watching 'Studio 60' on T.V. and they had a band that I thought was fictional called 'City of New Orleans'. I don't know about the band but the NBC site for Studio 60 had info on the players. The lead player is apparently Mervin Campbell and I've never heard of him before. Wilmer, or maybe Clarence---do you know anything about this guy? Here's the site:

You then have to go to the right side of the page, about 1/3 of the way down and click on 'A Musical Christmas Tribute' and 'Highlights'. You can also download the piece for free. Whoever this guy is, he did a beautiful and jazzy version of 'O Holy Night'.
