Screen capture from A Christmas Carol (1971) animated

This version of A Christmas Carol is one I remember very fondly from my childhood, and have lamented for many years that it wasn't being shown on television anymore.  Fortunately, a helpful YouTuber has uploaded the entire show.  Here we see two pipe-smoking lighthouse keepers celebrating and singing "God Rest Ye Merry Gentlemen" during the Ghost of Christmas Present sequence.

The full show is embedded below.
