"Happy Xmas (War is Over)" [John Lennon]

Worked on Patterns 1 & 2 in the Siver book. Worried it's going to get complicated. Went over my repertoire. In a couple of days I'll be playing Christmas music with a couple of bandmates at a coffee shop. There's been some friction in our church band regarding the appropriateness of us playing John Lennon's "Happy Xmas (War is Over)" in the spot after our Christmas Mass in the spot we usually play "Oh Christmas Tree." Apparently Lennon remains controversial after all these years. I arranged the Lennon song for the band, so of course I'm in the camp that wants to play the song. Yesterday I got disgusted, and gave up trying to argue to do the song, but then I changed my mind today. We'll be doing it.
