Extremes -
Eric Bogle's "Santa Bloody Claus"(sod him, his reindeer and his elves...) for what it says about the rapacious b******s who have turned the entire calendar into one long marketing opportunity.

"Jesus Christ, the Apple Tree" for its stunning beauty, simplicity and what it says about spirituality, even though I don't purport to be a Christian.

And just about any carol which can be played, sung and danced to with its original vigour...

Keep well,
Chris
