Very tough to keep the Christmas spirit with you throughout the year--especially as it gets warmer. Taking a note from Steven Pressfield and naming the inability to keep Christmas alive year-round, "The Resistance."
For me keeping Christmas alive with music throughout the year is just as much a spiritual journey as it is a mental and social one. It mirrors the struggle of the Christian commandment in Mark 12:28-32 to "love thy neighbor as thyself." It's incredibly easy to falter and let slip.
Still have not located a copy of John Denver and the Muppets TV special. Haven't really been looking very hard either. But I did pick up a used copy of Kylie Minogue's Kylie Christmas just based on the inclusion of a duet with Iggy Pop. It didn't do much for reviving the Christmas spirit because the Resistance is strong. However, I continue on.
