Guido has something good going on here with The Chipmunk's Christmas song chord melody. Even though he's arranged this with a standard high-G GCEA uke in mind, I gave it a whirl with both high-D and low-DGBE tuned baris. The arrangement was quite simple for me and a pleasure to play. It works for both high and low tuned ukes because the melody is driven by the high #1 string.
There is also a bit more challenging version 2.
