Steve Brown is an ex-merchant seaman...
I keep telling you, I was an Officer and a Gentleman

and had a man to clean my toilet.

I'm not sure about Deliverence or playing a banjo but I can hum the theme tune.
Some parts of Suffolk are like Deliverance country, lots of marrying your sister going on down Shotley way.

The Shoboat sounds like a few places I can recall. There was an interesting bar outside the dock gate in Montreal we used to call the Hairy Triangle as there was a strip bar upstairs. The bosun and a few deck hands got a bit lairy in there one night and a proper, wild west style fight started, with people whizzing down the bar, broken chairs, the works.
I pulled the Radio Officer out after some frenchy broke a chair over him. Oh! those were the days.
