Guaraldi brought in bassist Fred Marshall and drummer Jerry Granelli and re-recorded tracks such as "The Christmas Song" and "Greensleeves". The album credited Guaraldi solely, neglecting to mention the other musicians; Guaraldi was notorious for never keeping records of his session players. Nearly three decades later, in an effort to correct the matter, Fantasy surmised that the recordings with Budwig and Bailey were employed in the television special while Marshall and Granelli recorded the album. Despite this, other musicians have claimed to have recorded the special's music: bassists Eugene Firth and Al Obidinski and drummers Paul Distel and Benny Barth. Firth and Distil are noted as performers on a studio-session report Guaraldi filed for the American Federation of Musicians.
