Ahh, great to hear! It's not advanced but it sounds good, yes?
I have another Xmas song I could share... if I find the time...
I wrote down my own arrangement Rudolph The Red-nosed Reindeer for my students. Quite fun to strum this song, and to play the melody as well.
If you have a looper pedal, you can strum the chords, set it to loop and then play the melody to the loop.
