Just to answer a couple of points related to the Jazzer character: the actor is in fact a Scot, although I agree that he lays it on a bit thick. Anyone who'd lived in the west of England for as long as he has would no longer be likely to stick to the Scots pronunciation and dialect words as he does, as they'd so frequently fail to be understood.

And as to why we haven't heard him sing before: some years ago, Jazzer used to be a singer in a band with Fallon. An ill-advised experiment with the drug ketamine caused him to suffer some brain damage. How could they tell, you're asking? Well,after this incident it was alleged he could no longer remember the words to songs, so he stopped singing with the band. (Sudden thought: he could have carried on his singing in folk clubs, though, couldn't he?) The brain damage did not, alas, alter his tendencies to lechery and to extreme Scottish pronunciation (I'm not suggesting for a moment that these two are connected).

So either his brain has spontaneously regenerated its memory capacity, or this is a song he's known since he was a wee tot and it's never been erased from the database.

This has been a public sevice announcement for the information of Archers listeners everywhere.
