Ian,
very slight bias for 'Germany', but it doesn't really matter.
Could you please correct my error in Der Turm which Wilfried has pointed out? Easiest way is to replace my old note to that book by:

note: more than 500 songs with tunes and chords, but not annotated; attention: my fairly recent edition is still in a difficult to read handwriting print, I don't know if the very conservative boy scouts leadership considers compromising with modern times regarding the print
