It seems that the issue reared its head as a result of my "erroneous"
assumption that
\book {
Page layout stuff for front page
}
\bookpart {
Header & music
}
\bookpart {
Header & music
}
Was a way to go.
Although this has worked over the years it doesn't today.
If I just use \bookpart for each section all is well.
My trap was finding something that worked and using that as a template..
I have just tried another old file and that too has failed, so possibly a
recent minor change somewhere in Lily,Fresco,or Windows has highlighted my
original sin.
There is no profit in trying to find the reason.
