Swans of Wells - Swan Song

"Swan song" is a metaphorical phrase for a final gesture, effort, or performance given just before death or retirement.
 The Swans of Wells gave their final performance on 15th and 16th September when they were all gathered in the Bishop's Palace for a special public viewing prior to being auctioned on 29th September.
The auction will be live online, and you can bid on the Swans at this website.
