The song I mentioned, Yellow Girls is the Doodle let me go one.

'It's of a Captain's daughter belonged to Callao etc'

I have been struck by the similarity of some shanty tunes to Irish polkas which came in during the mid 19th century boom of Quadrilles across society worldwide. London, Bristo, Liverpool and Cork could be jumping off points


Dan Worrall has just produced a good book (2 vols)on the Anglo Concertina which explores playing in various comunities amongst which is the work on black African players who use songs as an essential part of all aspects of life.


He has done a lot of work , based in Texas.using digital archives . The section on the concertina at sea is excellent ( no evidence of concertina accompaniment to shanties but used in 'forebitters')
