"Must Be Santa" is a Christmas song written by Hal Moore and Bill Fredericks[1] and first released in November 1960 by Mitch Miller on Columbia 41814 (45 rpm).
[6] Following Brave Combo's lead, the lyrics in Dylan's version mix in the names of several United States presidents with a list of Santa's reindeer (e.g., "Dasher, Dancer, Prancer, Vixen / Carter, Reagan, Bush, and Clinton").
[7] Nash Edgerton directed an official music video for "Must Be Santa", described as "bonkers" by Martoccio, in which Dylan lip synchs the song at a raucous Christmas house party with other holiday revelers.
[9] "Must Be Santa" was also released as a music video ecard[10] and a 7" single, the b-side of which is a recording of Dylan reading 'Twas the Night Before Christmas that was first broadcast on Theme Time Radio Hour.
Based on Dylan's version, it updates the list of presidents to include both Barack Obama and Hillary Clinton.
