In some past year, I think I mentioned my affinity for the version of Deck the Halls that was given by Walt Kelly, in the 1960s, in his Pogo comic strip. Still, it bears repeating: "Deck the halls with Boston Charlie "Fa la la la la la la la la "Nora's falling off the trolley "Fa la la la la la la la la..." Then, I think the song says something about Don wearing gay apparel (whatever that might be). And then it speaks of trolling Carol in the yuletide season. I think that is all correct...
Truly a genius, how he fits 'his' words into the melody and makes it outstanding - even though it makes no sense. I love it!
