According to Google Maps, "Hopwood is a suburb of Heywood, a town within the Metropolitan Borough of Rochdale, in Greater Manchester, England", so that fits too. Thank you very much, Richard.

The last verse in my above transcription has a typo; "boom" of course must be "bloom".

I understand that the lyrics are printed in MacColls Book "Shuttle and Cage". Unfortunately I don't have the book, only the same-named LP. If somebody should have access to the book, can he/she please give us the printed version?
