So grab your rose and ring side seat
We're back home at Potters Bar

The story:

Potters Bar is a quiet, upmarket, commuter town near
London. For a while this song did not convey the
image of lurking menace and prowling vampires at
night. I thought of packed commuter trains chugging
out of Euston to take the weary commuting workers
home. Also, a Redcap, in Britain, is a military
policeman. To any one who has done time in the Army,
this trumps the intended **sociation with
(hallucinogenic mushrooms?) intended in the song...
cultural difference there, rather than a misheard...
