I have three of his Christmas Albums. The new one from this year isn't as good as the old ones but Yabba-Dabba Yuletide is an instant classic!
I actually never listened to any of his Xmas albums. I should add them to my Spotify playlist.
For those interested, at midnight Spotify added The Beatles catalog to their database. Now, I just need them to add King Crimson, Steven Wilson, and Neal Morse-related recordings and I'll be happy.
