When I was an impressionable teenager Merthyr was blue. It was the height of the hooligan era late 80s / early 90s and it was certainly not a safe place for the few Jacks in town. Supporting Swansea was not something you broadcast around Merthyr in those days.

These days since the 7 years the Jacks spent in the PL there’s a lot more Jacks in Merthyr. I’d still say the town was blue but not the large majority that it used to be.
