The glo'al stop was used a lot in Salford (Lancs) back in the 50s and 60s, but largely by kids who wanted to be considered a bit hard. I can't recall adults using it. There was also another linguistic variant... much of Salford was deprived, but Bringle Eaf (Brindle Heath) was considered even below Hanky Park. The inhabitants used to have cangles in bockuls on the manklepiece.
