Let's take another look at this video, which we posted last year at Chistmas: Dr. John joins Leon Redbone for a duet of "Frosty the Snowman."  The track originally appeared on Redbone's 1987 Christmas Island album. The video below was recorded during a 1990 airing on the Night Tracks TV show, which appeared on SuperStation WTBS from 1983-1992. It's sweet and charming and contains epic snowball fight footage.
