Alan Freeman presents an additional Saturday Show running from 11.00 pm to 12.00 midnight (an hour at which Radio 1 did not usually broadcast at that time on Saturdays; this followed the simultaneous broadcast with BBC2 of the Kinks' Christmas concert, and Alan had hosted his usual three-hour show earlier that day featuring the year's quadrophonic sessions).
Fluff mentions saying Merry Christmas to John Peel and his family before playing the Faces track.
Fluff gets Tony Wilson to say Merry Christmas before the end of the show.
The available audio - the full hour-long extra show plus the midnight Radio 2 News - consists entirely of album requests from listeners.
