I've just googled for Mrs Binns Twins - it seems to have been a comic song performed in the 1930's by Gracie Fields ... I haven't been able to find much reference to it (as yet). "The Wreck of the Hesperus" was a phrase well used in our family ... I was aware that it derived from a poem, but until wld just posted them, I had never seen the words.
So Mrs Binns Twins were unknown to our Surrey family ... maybe they just weren't Gracie Fields fans??
