I've been binge watching that old tv sitcom from 50 years ago and finished it up yesterday. I remembered a scene but never realized it was the very last scene of the last episode of the series (which was a cute series I was glad to watch again). The very last scene of the whole series - Richard Long singing part of "Three Jolly Coachman," then giving a wink.
I don't think I've ever heard anyone other than KT sing Three Jolly Coachmen before. Have I missed somebody somewhere?
