Sorry to put a damper in, Mick and Fred, but there's a lot of dodgy stuff in Christie. He was a follower of the fabricator, Peter Buchan, and you'll find a lot of duplication of Buchan's materiasl regurgitated in there. he also appears to have added a lot of his own music in as well. There may be genuine stuff in there but it would be impossible to say what was genuine and what was Christie's and Buchan's own compositions. I know I'm the ultimate superskeptic but a lot of serious scholars will tell you the same.

If there wasn't so much dodgy stuff in there £30 would be a bargain for the bindings alone!
