CJB, I suggest that, when you are able to obtain recordings of the programmes, you listen to them. The points you make are fully answered. The programme maker, Mary Owens, consulted Sean Corcoran, Lillis Ó Laoire and many others, including me, in the course of the compilation and between us we know, not only about Irish songs, but about songs, maritime or otherwise, from across the English speaking world. This is not to assert total accuracy or balance. However, I can discern no kind of strangeness in what has been presented and , in Ireland, what other kind of singing style would you expect.
