I do an instrumental to "Sleigh Ride." This from Wikipedia:

According to the American Society of Composers, Authors and Publishers [ASCAP] review of Christmas music, "Sleigh Ride" consistently ranks in the top 10 list of most performed songs written by ASCAP members during the Christmas season worldwide.[1

On the PSR-S910, I use a purchased style called French50's, and I use a variety of great voices on the right hand. I use a Xmas multipad on a lot of my Xmas tunes to get that sleigh bell sound.
