My great-(great?)-grandfather was an Irish tailor who upon arrival in Newcastle set up shop on the Castle Garth Stairs, noted in the Traditional Tyneside song A U Hinny Bird for an associated with the trade:

The quayside for sailors - A U Hinney Bird
The castle garth for tailors - A U A
The Gateshead hills for millers - A U Hinney Bird
The north shore for keelers - A U A

The old shop fronts are still there...
