No. I don't sing along if I don't like the lyrics or it's not relevant, support comes in many guises my friend. I've done more than my fair share of supporting in the last 44 years.
As for the TEYN thing, still none the wiser but thanks for trying.
Apparently if you are unaware of the 'teyn' bollocks then you ain't a true Northamptonian I have been told by the Husk. I can go back at least 4 generations of my family living in Northampton and although I have managed to escape I have absolutely no recollection of the term.
