Please don't tell me that Chip Davis and the gang are not conservatives! I never really looked into their politics but kind of assumed they were on our side being that they were from Nebraska and Rush was such a big fan of them.
At any rate, their first three albums are among the greatest Christmas recordings of all time. I never get tired of hearing them. However, their more recent albums have been major disappointments to me, especially last year's "Christmasville" which was utter junk and totally unrecognizable from their earlier output. In fact that is one of only two Christmas albums I ever had to junk after buying them - the other one being the soundtrack to the horrible Jim Carrey version of "Grinch that Stole Christmas."
Ten more songs at random from my collection...
Mary Had A Baby - Bruce Cockburn
Winter Wonderland - Phantom Planet
What Child Is This? - Balderas & Osborne
True Believers - Melanie
Country Christmas - Loretta Lynn
Star Of Bethlehem - Angels & Airwaves
Last Christmas - Jimmy Eat World
Skating On The River - Lily Frost
Frosty The Snowman - Jimmy Durante
A Change At Christmastime - The Flaming Lips
No Burl Ives?
Christmas (1984)
A Fresh Air Christmas (1988)
Christmas in the Aire (1995)
Christmas Extraordinaire (2001)
My two favorite pieces from the four albums are their rendition of Stille Nacht (Silent Night) (still the most beautiful version of this song I've ever heard) and Davis' original composition "Traditions of Christmas" (which captures the feeling of Christmas morning like no other composition I've ever heard). 
"Joesph and Mary's Boy" is a must at the Bear Cave.
