The original book was printed from a home computer. That has then been
taken apart re runthrough an automatic feed sacanner to produce a file of
397 PDF pages (171Mb). Each page has several songs distributed over two
columns.

By uing !PDF and zooming the view up mightinly I was able to take a
screen shot of just he song I wanted. 

Running that through ChngeFSI at monochrome resulted in a block of black
instead of text unless I set the output to 256 colours. Then Sleuth3
worked.

The output wasn't brilliant due to the imitations of te original.

I couldn't find a way of sending a single page to CView and running the
whole thing caused GView to stop with a window of multiple error messages.
