After being left off all of the Beatles' annual Christmas fanclub records, the song "Christmas Time" appeared as a B-side to what "lost" single?
Christmas Time (Is Here Again): "Christmas Time (Is Here Again)" (Lennon/McCartney/Harrison/Starkey) is a Christmas song recorded by the Beatles for their 1967 fan club Christmas record. Christmas Time (Is Here Again):  After being slated for inclusion in the planned (but ultimately scrapped) "Sessions" compilation album in 1985, the song finally saw official re-release in 1995 on the "Free as a Bird" single (issued in conjunction with the "Anthology" series), for which it was edited from its original 6:17 to a shortened version of 3:03. The Beatles' Christmas records:  One such record was issued each year from 1963 to 1969 and an LP compilation of all seven in 1970.
