outputting multiple parts from a score and 1 is not is not output

[chip]

So as mentioned in a previous message I got this working - outputting 
multiple parts from a score. I just discovered that I am not getting all 
the parts defined. I have a 6 part score, use the \book command for 6 
different instruments, but lily only creates 5 .pdf files. It is 
ignoring the first instance of the \book command. I tested this by 
changing the instrument defined in the first \book instance, and each 
time the first \book is ignored. My file is pasted in below.
