The Dixon tunes - even the 8-note ones which ended up on NSP, all are notated with a flat 7th.
Er...I don't think so.
Here's the beginning of "Hit her between the legs"
There's a key sig of sorts there, but it's open to interpretation.
More importantly, I've just noticed something. The title has been overwritten, and the date beside it is in the second hand. I'll have to get back and look at some more of it, but the original hand on this page at any rate, is earlier (and more ornate). I am thinking this may be Percival's master work to get his freedom - 1697.
Aaargh!
