If anyone's interested in "Parlour" sea-songs try getting hold of a copy of Ashton's "Real Sailor's Songs" (the word "Real" is somewhat of a misnomer), John Foreman produced a re-print of it about 20 years ago. It's basically a set of bound broadsheets and besides the songs a great source for wood-cut illustrations. I don't think there's any Dibdin in it though. Mind you I also once heard Stan say that he thought some sailors did write the odd song to sell on the shore - a bit like musical scrimshaw !
