Bert - "The Rorty Crankle" which was at Plaxtol was closed down the last time I drove past.

There's a pub near Plumstead Common called "The Who'd 'a thought it".

I'm surprised that Leadfingers didn't mention the "Crown and Treaty" where Uxbridge folk club runs. Originally called "The Treaty House" it was the site of an unsuccessful attempt to draw up a treaty to bring an end to the Civil War.

Central London has some interesting pub names:
"The Crown and Two Chairmen" - there's also a "Two Chairmen",
"The Magpie and Stump",
The famous "The Olde Cheshire Cheese" (rebuilt in 1667 - I wonder why),
"The Sun and Thirteen Cantons".

Near Hextable, Kent, there is a pub called "The Ship at Puddledock" which sounds very nautical except that Puddledock Lane which is the reason for it's name is nowhere near the sea or any waterway.

I have heard that the reason why so many pubs in SE England are called "The Chequers", is because of the "Chequer Tree" (Wild Service Tree) from the berries of which a form of ale was brewed in the autumn.
