Multiple Scores with different composers, poems and titles

[Sebastian Werk]

Hi,

I tried to combine multiple scores of different composers and/or poets in one 
(Christmas) Songbook. The only way having the composer, poet and title printed 
at the beginning of each song was to use

\paper {
  print-all-headers = ##t
}

This resulted in much bigger spacing between title and score than usual – I 
suppose space for subtitle etc. was reserved. It would be nice, if in case of 
using the print-all-headers-switch, the generation of the headers would work as
it works when setting up one single song.

I hope I did not have overlooked something and wasted your time…

Best regards

Sebastian

P.S. Using \bookpart is no workaround in my case, since the songs are usually 
very short.
