Thanks - I've now tested out setting system-system-
spacing.stretchability and I'm pretty sure most people would find the
default value 

system-system-spacing = #'((basic-distance . 12) (minimum-distance . 8) 
(padding . 1) (stretchability . 60))

which is in paper-defaults-init.ly to be *much* too high (60 => 2 ??).
And I see that the markup to score stretchability also needs to be much
reduced to prevent the titles appearing at the top of the page and the
music much lower.

Thanks again to all who helped.
