There’s an interesting article here: The Tatty Mob
It mentions “songs of the Tatty Mob” which makes me think that there could be more than one. The meeting advertised never took place, of course, because of Covid, and Jim himself died later that year the same disease.
I wonder if Elizabeth might be able to get some more info from Hull City Council or Hull public libraries? The article also mentions that Jim had written a book: possibly any songs might be in that? (It doesn’t give the title, but does anyone here have a copy?
