After playing some gigs with the "Holiday 100" set this holiday season, I've noticed how many songs in there have non-standard chord changes. I hesitate to call them "wrong," because they musically work, but they're not the common or original changes to many of these songs. I updated all of them with either the standard changes I've encountered over the years or the original changes for songs where you can point to a specific, original, iconic recording. I also added all of the Vince Guaraldi "Charlie Brown Christmas" songs plus the "Grinch" song. Lastly, I removed the "jazz" versions of the songs as they seemed claustrophobically reharmed, especially since many of the original changes are quite suitable for jazz as-is without needing to throw in the everything and kitchen sink.
