re: "Blue" venue?

[O]

There's a pub in Covent Garden in London called 'The Crown and Anchor' - I
think it's quite a common name for pubs here in the U.K, but maybe (just
maybe) Joni stopped in for a drinking session on her travels in 1970 and
wrote 'Blue' while drowning her sorrows (to keep up the nautical theme)...
unlikely, but it's a thought!
