Beware of Storm Boris, it'll be a lot worse!

Jim,
This is a genuine suggestion and you may already have done it. Dave Hillery's thesis is readily available online. Just Google 'Dave Hillery Thesis'. It's a longish read but well worth it. And contrary to what I said elsewhere it is very academic, very knowledgeable and very well researched, BUT accessible to the likes of thee and me. He compares the lives and repertoires of Jack Beeforth (N Yorks), Walter, Frank Hinchliffe (West Yorkshire) and Joseph Taylor (N Lincs). It even mentions the contributions of one Jim Carroll.

I would be very pleased to read your thoughts on it.

Non-compartmentalisation or compartmentalisation of repertoire have got sod all to do with a singer's intelligence or worldliness. it is affected by a whole set of factors.
