Santa Claus is Coming to Town from 1964. This is a weird track. It’s the only Christmas tune buried on Evans’ Trio 64 album released in January 1964. I'm guessing it is a live recording from the holiday season of 1963.
The song starts with this odd, loping, off meter melody. Go ahead and tap your foot to the beginning of this song. The whole thing is quintessential Bill Evans. It's so easy to cover traditional holiday music.
