I don't know the episode but what a great idea for a coffee/tea room I for one would love to visit .
Is it the boat that the Commodore was on in THE FLAG AND ITS SNAGS (Foggy was on the towpath calling "Permission to come aboard sir !"
The Swan Man of Ilkley with Tommy Cannon at the helm?
The Black Widow
Sweet smell of excess ??
