What you're not allowing for is that where you say a song is from, may be part of where you want to take it.

I can see that such a subject might be of overwhelming concern to an academic or an educator like Brian who doesn't wish to impart false information.

its amazing rthough how people will warm to a song if you tell them its from their local area. Sometimes they even tell you they knew the writer, even if you've got your facts all wrong.

The artist must surely take the version of the song he feels most able to 'sell' to the audience - however unsatisfactory its provenance. That's my instinct at least, and I wouldn't be surprised if these considerations crept into Lloyd's considerations.

Even if he didn't leave a record of himself thinking like this - isn't it how all singers think?
