Many thanks for all the suggestions so far.

Still hoping for a Grimsby contact...

Reading the related thread (underway), the last post mentioned that the christmas lights are turned off every 19th Dec. as a mark of rememberance.   This jogged my memory to the start of one of the verses first line.

'No christmas lights in Mouse'le show'    and later    'remember now the lifeboatman who works for charity'

Moving words when you know the story...
